Quick setup for VoIP Conference Calls  
While all components delivered with the Revolabs FLX2 Conference Phone are partially  
charged, we recommend charging the Speaker, the Microphones, and the Dialer for at  
least 8 hours or overnight before starting to use the system.  
Connecting the Base Station  
Place the Base Station close to the Ethernet outlet  
you want to use for the conference phone.  
Connect the Base Station to the network using the  
provided Ethernet cable. The Base Station is  
powered using Power over Ethernet (PoE). This  
requires your Ethernet outlet to provide PoE.  
Please check with your IT department that PoE is  
available. If the base station does not power up  
after you connect it to the network outlet, this  
outlet might not be providing PoE.  
If your network does not support PoE, please  
contact your reseller. Revolabs provides a power  
injector that can be bought through your reseller,  
which adds the necessary power to that Ethernet  
connection.  
Connecting the Charger Base  
To switch on the microphones  
Place the Charger Base at a location where you  
can easily access the Microphones and the  
Speaker for your conference calls, e.g. on a side  
board, a desk, or the conference table. Connect  
the Charger Base to the power outlet using the  
provided power supply. Place the Speaker, the  
Microphones, and the Dialer in the respective  
openings of the Charger Base to charge them.  
The Dialer and Speaker will automatically connect  
to the Base Station after a short time if it is  
powered up. You will hear a confirmation chime  
from the Speaker once the system is ready for  
use. If the Speaker or the Dialer is not powered  
up, take them out of the Charger Base for a few  
seconds and put them back in. This will switch on  
the component.  
take them out of the charger  
base. They will automatically  
power up and connect to the  
base station.

VoIP configuration  
For the FLX phone to work within a VoIP environment the phone has to be set up to  
communicate to the telephone switch. You will also have to enable the extension (user)  
you want to use with the FLX on your switch. Please review your switch documentation  
on information on how to do that. For the minimal setup, in the FLX Handset you will  
have to provide information on the IP connection to the telephone switch. To do this  
visit Setup – Advanced Setup – Network Settings – VOIP Settings. Under Registrar,  
provide the IP address or host name of your IP PBX. Username should be the  
extension or name under which you want to register this phone on the IP PBX. In  
Password, provide the password for this username. If no values are provided for ID and  
Display Name, the Username entry will be used for them. Select ‘Reload Settings’ after  
you have set the values in the handset, which will restart the base.  
For enhanced settings the Web Interface provided by the FLX needs to be used. Go to  
page 49 for a description of the web interface.  
Making a call  
To make a conference call, take at least one of the Microphones out of the Charger  
Base, and take the Dialer out of the Charger Base. You can remove all Microphones  
and the Speaker if you wish, but this is not required. Use the Dialer to enter the number  
you want to call, including any leading digits your VoIP telephone switch might require.  
The Speaker and any Microphone that is not in the Charger Base will be active during  
the call. To finish a conference call, press the red hang-up button on the Dialer.  
NOTE: It is also possible to have a conference call with the  
microphones in the charger base. However, due to the  
proximity of microphone and speaker at that time, audio  
quality might be impacted. The maximum volume of the  
speaker is limited while the microphones are in the charger  
base. Microphones that are placed into the charger base are  
switched off. To use microphones in the charger base for  
phone calls they first have to be switched on. You do this by  
pressing the button on the microphone while it is in the  
charger. The microphone will start in a muted state. Once it  
starts blinking red, unmute it by pressing the mute button once  
again. Microphones in the charger base never transmit audio  
to the AUX OUT connector. If any microphone is active  
outside of the charger base, microphones in the charger base  
cannot be activated (unmuted) for the call.  
To make a call using the Dialer as a handset, make sure that all Microphones are in the  
Charger Base before starting to dial the number. At this point, only the Dialer will be  
used for the call. To end the call, press the red hang-up button on the Dialer.  
At any time during a call you can toggle between handset and conference phone mode  
using the buttons on the Dialer.

To answer a call using the conference phone, simply remove one or more Microphones  
from the Charger Base when the Speaker rings. If a microphone is already out of the  
charger base when an incoming call comes in, pressing the button on the microphone  
will answer the call in conference phone mode. You can also use the Dialer to answer  
the call by pressing the green call button on the handset. If all microphones are in the  
charger at this time, the call will be answered using the handset mode. If at least one  
microphone is switched on and not in the charger base, this will answer the call in  
Conference phone mode.

are equipped with a button for pairing and muting, an LED indicator to display mute  
status and battery charge level, and an internal buzzer to warn if the Microphones have  
lost connection to the Base Station.  
The FLX Microphones, shown below, come in three different versions to provide a  
flexible solution to meet all applications of conferencing spaces. Microphone types  
include an omnidirectional tabletop Microphone, a directional tabletop Microphone, and  
a wearable lapel style Microphone. Any combination of two FLX Microphones can be  
used with a FLX2 System as they are mix and match.  
FLX Microphones will operate in or out of the Charger Base. It is recommended to  
always remove the microphones from the charger tray for conference calls as audio on  
the speaker and the microphones is limited while in the charger base. When using  
Microphones in the charger tray system behavior is automatically adjusted to the close  
proximity of speaker and microphones. See the note on page 8 on how to activate  
microphones in the charger.

Initial Setup  
After unpacking the FLX2 Conferencing System, there are a few initial setup tasks that  
must be performed before a call can take place or any system configuration can be  
changed.  
Connecting System Cables  
The FLX2 Charger Base has a power supply that needs to be connected, as shown  
below. In addition, the Base Station needs to be connected to the network using the  
provided Ethernet cable before a conference call can be made. The FLX unit expects  
Power over Ethernet (PoE) to be provided through the network connection. If your  
network does not support PoE, a power injector is required. Please contact your  
reseller to purchase the additional PoE power injector. The Base Station offers  
additional optional connections that are only being used when the FLX2 System for  
example is connected to a video conferencing unit or a recording device. The cables  
required for these connections are not included with the FLX2 system and need to be  
purchased separately.  
VoIP configuration  
For the FLX phone to work within a VoIP environment the phone has to be set up to  
communicate to the IP PBX. You will also have to enable the extension (user) you want  
to use with the FLX on your PBX. Please review your PBX documentation on  
information on how to do that.  
From the FLX Handset  
Depending on your IP PBX, different settings will be required for your FLX to work in  
your environment. First, the FLX will require an IP address. The IP address can either  
be obtained from a DHCP server in your network, or be statically set on the phone. The  
phone is preset to DHCP. If you want to change this setting, open the menu on the  
Dialer by pressing the right soft key, go to the “Setup” menu, and select “Advanced  
Setup.” You will have to enter a password, which is preset to 7386. Switch DHCP OFF,  
and then select “Network Settings.” Under “IP Settings” you can set the required  
15  
Download from Www.Somanuals.com. All Manuals Search And Download.  
network values like IP Address, Subnet Mask, Default Gateway, and DNS Servers. You  
will need to restart the phone for any changes you made in this section to take effect.  
If you are using DHCP, you can go to the System Info menu, and select About System.  
The assigned IP address for the FLX will be shown here.  
Independent on how the IP address of your system was assigned, the FLX phone has  
to be configured to work in your VoIP environment and communicate with your IP PBX.  
You will have to enable the extension (user) you want to use with the FLX on your IP  
PBX. Please review your IP PBX documentation for information on how to add and  
configure users. For the minimal setup, in the FLX Dialer you will have to provide  
information on the IP connection to the IP PBX. On the Dialer visit Setup – Advanced  
Setup – Network Settings – VOIP Settings. Under Registrar, provide the IP address or  
host name of your IP PBX. Username should be the extension or name under which  
you want to register this phone on the IP PBX. In Password, provide the password for  
this username. If no values are provided for ID and Display Name, the Username entry  
will be used for them. Select “Load Settings” after you have set the values in the Dialer,  
which will restart the Base Station.  
For enhanced settings the Web Interface provided by the FLX needs to be used.  
From the FLX Web Interface  
If further settings are required to connect the FLX phone to your IP PBX, like a Proxy  
server, please visit the FLX Web Interface. You get to this interface by entering the IP  
address of the FLX into the web browser of your choice. After you enter the password  
(7386, unless you changed it in the Dialer), you can find the SIP settings under the  
Administrator tab on the top right. You will find the different SIP settings under SIP  
Registration, SIP Configuration, Transport, and Media. You have to press “Save” on  
every page where you changed an entry to save these changes. If you do not press  
“Save,” the changes will be lost when you leave that page. Restart the phone once you  
are finished with your changes. Please see page 49 for a description of the FLX Web  
Interface.  
Managing A Call  
The FLX2 Wireless Conferencing system is equipped with a VoIP interface that allows  
the system to make conference calls in a VoIP network. The following are the basic  
operational instructions for making and receiving telephone conference calls.  
Calling Configurations  
The FLX2 Wireless Conferencing system has the ability to make and receive calls in  
many different ways. This provides the caller the ability to choose what mode or call  
type best suits the needs of each individual call.  
Speaker Mode  
Speaker mode allows the call to take place using the Speaker and Microphones  
provided with the FLX2 System. This allows multiple users, within the conference room,  
to participate in the call. It also provides the ability for the Microphones and Speaker to  
be located anywhere in the conference room to meet the needs of each meeting. The  
16

call, as well as the Speaker and Microphones, are controlled by the FLX Dialer. The  
user can switch between ‘speaker mode’ and ‘handset mode’ while in a call.  
Handset Mode  
Handset mode allows a telephone call to take place through the handset speaker and  
microphone located in the FLX Dialer. This allows a single user to make and receive a  
private call. It also provides the ability for the FLX2 System to act as a personal desk  
phone. The Microphones and Speaker are not used during a handset call. The user can  
switch between ‘speaker mode’ and ‘handset mode’ while actively in a call by using the  
key marked ‘‘Handset’ or ‘Speaker’.  
NOTE: To switch from a handset call to a speaker call at least  
one Microphone should be out of the Charger Base and  
switched on, and the Speaker must be switched on. If all  
Microphones are in the Charger Base at least one of the  
Microphones in the Charger Base has to be activated manually  
by pressing the Microphone button before switching from the  
handset call to a speaker call.  
VoIP Call  
The FLX2 Conference Phone allows making conference calls using an Ethernet VoIP  
connection. A telephone call can be made using either ‘speaker mode’ or ‘handset  
mode’. A telephone call can be made at the same time as a video call. Telephone calls  
are controlled via the FLX Dialer.  
Bluetooth Call  
The FLX2 System is equipped with a Bluetooth interface that supports the Hands Free  
Profile (HFP). This profile allows the user to make a call through a cell phone, a  
computer, or other device via a Bluetooth connection. A Bluetooth call can be made  
using ‘speaker mode’ only. A Bluetooth call is controlled by the connected Bluetooth  
device. A Bluetooth call can be made at the same time as a video call.  
NOTE: Revolabs FLX only supports the Hands Free Profile  
(HFP) for Bluetooth 2.0 or higher. Applications that try to use  
the Bluetooth connection not using the HFP profile, or that are  
using an older HFP / Bluetooth standard are not supported by  
FLX.  
Video Conference Call  
The FLX2 System can be connected to a 3rd party video or PC conferencing system via  
the Analog I/O ports located on the FLX2 Base Station. This allows the Microphones  
and Speaker to be used as the audio interface for the video conference call. Video  
Conference calls are controlled primarily by the video conference system. However,  
audio properties can be controlled via the FLX Dialer. While the FLX2 Conference  
Phone is connected to a video conferencing device, it might still make and accept calls  
over the VoIP connection or via a Bluetooth device.  
17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
NOTE: When using the FLX connected through the AUX IN  
and AUX OUT to another device, only the FLX speaker can be  
used. All other speakers, e.g. in a television set, must be turned  
off. To avoid audio problems, any Echo Cancellation provided  
on the Video Conferencing unit should be switched off.  
NOTE: For security reasons, Microphones will not send any  
audio signal to the AUX OUT connector when in the charger.  
To receive audio signal on the AUX OUT, microphones have to  
be taken out of the Charger Base.  
FLX Home Screen  
Whenever the FLX is not in a call, the FLX Dialer will  
show the FLX Home Screen. The Top of the home  
screen shows several symbols, indicating the current  
status of the FLX components. From left to right they are  
an indicator for the Speaker, one symbol for each of the  
mics, and a charging indicator for the handset itself. The  
color of the Speaker and Microphone symbol indicate  
whether the system is available and unmuted (green),  
available but muted (red), switched off (grey), or the  
current status is unknown, e.g. when the component was  
taken out of range (yellow). The handset charging  
indicator shows the current status of the battery. Green  
indicates a charged battery, yellow means that the charge  
is getting low, and red indicates that the battery requires  
re-charging. In the Charger Base the battery indicator will  
show a grey symbol while charging.  
In addition, the first line will show if a Bluetooth link is  
currently active with a blue symbol. If the Handset failed  
to connect to the Base Station, a red, crossed out  
Bluetooth symbol is shown.  
In the top text line of the screen the ID or the user name  
with which this telephone registered to the VoIP PBX is  
shown. Below that, current time and date are displayed.  
From the home screen a call can be started by dialing a  
number, The “Do not Disturb” function of your switch can  
be activated for this phone, or the system menu can be  
entered. Whenever “Do not Disturb” is turned on, all calls

to this phone will be handled in the switch as defined in  
there, e.g. sent to voice mail,  
The Home screen also provides information on new voice  
mails for the extension (if available), and on missed or  
rejected calls.

Component behavior in and out of the Charger Base  
Each system component will respond differently when placed in or out of the charger  
during an active telephone call. The following is a description of what can be expected.  
Dialer  
When the Dialer is placed into the Charger Base during a call in ‘speaker mode’, the call  
will not be affected and the Dialer will enter its charging mode.  
When the Dialer is placed into the Charger Base during a ‘handset mode’ call, all calls  
(even calls that are currently on hold) will end and the Dialer will enter its charging  
mode.  
When the Dialer is removed from the Charger Base no change to call activity will take  
place. If there is no active call, the Dialer will revert to the home screen.  
Speaker  
When the Speaker is placed into the charger during a call the Speaker will reboot and  
enter its charging mode. During the reboot the incoming audio from the conference call  
will mute until the reboot is complete (approximately 6 seconds). Once the reboot is  
complete the audio will resume on the speaker.  
When the Speaker is removed from the charger no change to call activity will take  
place.  
Microphones  
When a Microphone is placed into the charger during a call it will automatically reboot,  
switch off and enter its charging mode. If all Microphones are placed into the charger  
during a speaker call, all Microphones will switch off and the call will automatically  
switch to handset mode. To return to a speaker call a Microphone in the charger base  
will need to be manually switched on by pressing the mute button, and then unmuted by  
pressing the button again. The call will need to be switched over to a speaker call using  
the dialer. It is not recommended to use the Microphones in the Charger Base for a  
speaker call.  
If at least one Microphone is outside the charger base active, the Microphone in the  
Charger Base cannot be unmuted.  
When a Microphone is removed from the charger, it will automatically power on and if  
“Start Unmute” is ON, unmute itself. If there is an incoming call when a Microphone is  
removed from the charger the call will automatically be answered.

Bluetooth  
The FLX2 System is equipped with a Bluetooth interface allowing a call to be placed  
through a cell phone, computer, or 3rd party Bluetooth device. The FLX Microphones  
and Speaker then act as the Microphone and Speaker for that call.  
The FLX2 System only supports the Hands Free Profile for Bluetooth 2.0 or newer.  
Should the application on the computer, cell phone, or other 3rd party device require  
other profiles to be supported, FLX cannot act as the Speaker and Microphone for that  
application. Please contact the provider of the application to find out which Bluetooth  
profile can be supported.

Video Conference Collaboration  
The FLX2 System is equipped with balanced analog audio input and output to be  
connected to 3rd party video or PC conferencing system. This allows the FLX  
Microphones and Speaker to be used as Microphones and Speaker for video calls. It  
also provides Acoustic Echo Cancelation and Noise Control to the video call.  
Connecting a Video Conference System  
In the advanced audio setting (see page 43), change the Aux Audio setting for Aux Out  
to MIC. Then connect one of the AUX OUT on the FLX2 Base Station via an  
appropriate mono balanced or unbalanced cable with 3.5mm plugs to the ‘Mic Input’ on  
the video conference system.  
The line level audio AUX IN on the FLX2 Base Station should be connected, via the  
appropriate mono balanced or unbalanced 3.5mm cable, to the ‘line output’ of the video  
conference system. See page 71 for a list of audio cables required for the most  
common video conferencing systems available in the market.  
As the FLX system provides the Echo Cancelation for the call, any Echo Canceler in the  
Video Conferencing unit should be switched off. Not switching off the Echo Canceler in  
the Video Conferencing unit might negatively affect the audio on the FLX Speaker and  
Microphones. Please visit the documentation of your video conferencing unit on how to  
disable the Echo Canceler.  
Any audio device like external speaker or TV speaker attached to the video  
conferencing unit needs to be disabled. The FLX Speaker and Microphones become  
your only audio devices for the Video Conferencing call. Any other devices will affect  
the Echo Canceler and will cause negative impact on the audio of the call.  
NOTE: For security reasons the FLX Microphones will not  
send any audio to the AUX OUT while in the Charger Base.  
The microphones have to be removed from the Charger Base to  
send audio data to the AUX OUT connector.  
Configuring the Analog Audio  
For best audio results, the AUX IN and AUX OUT connectors have to be configured in  
the right way to receive best results with your video conferencing unit. This requires  
testing and setting of the values in your environment. See page 39 on setting the  
volume for the AUX IN and AUX OUT connectors and how to set the level (microphone  
level or line level) for the AUX IN connector.  
Making a Video Call  
The FLX2 System acts as a wireless Microphone, Speaker and mixer for the video  
conference call. Once configured, a video call can be made using the 3rd party user  
interface supplied with the video conference system. Simply remove the Microphones  
from the charger to activate the analog audio input.

Mixing the audio signals  
As discussed earlier, Audio and Video, or Bluetooth and  
Video calls can be made simultaneously from a FLX  
system, requiring FLX to mix the audio of the different  
inputs to go to the different outputs.  
In the Audio Controls menu, available from the main menu  
and the Active Call Menu, the Audio Mixer menu is offered.  
This menu offers three different audio mixer settings, based  
on the output medium. The Speaker Mixer shown allows  
defining the mix between AUX IN and the Phone input to be  
played back on the Speaker. It is a sliding scale from -8 to  
+ 8.  
Similar Mixers are offered for Phone Out (mixing the signal  
between AUX IN and the microphones), and AUX OUT  
(mixing the phone input and the microphones).  
The mix of audio can be changed during call time to ensure  
that the various outputs best reflect the audio requirements.  
The mixer menus do not replace the AUX IN and AUX OUT  
volume settings described on page 40.

Pairing  
All FLX2 wireless components are paired before the system is shipped, providing much  
of the system setup already completed. While pairing should not be required for the  
system to work, sometimes components can require pairing if a part is shipped  
separately.  
The following are instructions on how to pair the wireless components of the system to  
the FLX2 Conference Phone. All components are paired to the Base, which is the  
central unit that communicates with all other components. To pair a Microphone or a  
Speaker to the FLX Conference Phone, a FLX Dialer has to be paired first. If several  
components need to be paired, or a whole system needs to be paired, start with the  
FLX Dialer.  
Dialer  
1. Turn off the Dialer by pressing and holding the red ‘end call’  
button until an overlay appears asking whether you want to  
shut the Dialer down. Press ‘Yes’.  
2. Plug in the FLX2 Base Station.  
3. Turn the Dialer back on (press the red ‘end call’ key). The  
screen should read “Scanning for new base”. If the screen  
reads “scanning for paired base”, press the ‘Stop’ button,  
press the ‘Menu’ button, navigate to “Advanced’, and select  
‘Re-Pair’. When asked whether to ‘Scan for New Base’,  
select ‘Yes’.  
4. After some time scanning for available bases, an overlay will  
appear asking ‘Pair with <System Name>?’ The system  
name is either the Factory preset name of RevoFlxxxx, with  
xxxx the last 4 digits of the BT number on the bottom of the  
Base station, or the system name you previously selected in  
the Advanced Setup. Select ‘Yes’.  
5. An overlay, ’Pairing with base <System Name>’, should  
appear followed by a ‘Connecting…’ and then and  
‘Initializing…’ screen. Shortly after that the Dialer home  
screen will appear. Your Dialer is now paired.  
6. If the Dialer does not automatically pair, repeat steps 1-5. If  
this still does not resolve the problem, select “Reset Factory  
Defaults” under ‘Advanced’ as this will force a scan for a new  
base.

Static IP Settings  
Static IP Address The Static IP Address is the IP address that the network  
administrator has assigned to the phone.  
Subnet Mask  
Subnet Mask is used to determine the subnet to which the phone  
belongs, for example, 255.255.255.0.  
Default Gateway The Default Gateway is the phone’s default router on the IP  
network. It is usually the router connecting the internal network with  
the outside network.  
Domain Name  
Primary DNS  
Server  
This is the network domain name.  
This is the address of the primary Domain Name System (DNS)  
server that translates domain names into IP addresses. Sites often  
configure a primary DNS server and a secondary backup DNS  
server.  
Secondary DNS  
Server  
This is the address of the secondary DNS server.  
SIP Registration  
The SIP Registration page is used to configure the SIP registrar and proxy settings and  
the SIP account and user settings for the phone. The minimum number of information  
required to register your phone is the Registrar, the Username and Password. If ID and  
Display Name are not set, FLX will use the user name for both of these parameters.  
Some IP PBXs an ID different from the user name to be set. You must register  
successfully to the SIP registrar before you can make calls with your FLX.  
The figure below shows the SIP Registration page. After changing any settings, the  
changes must be saved and the phone must be restarted for the changes to take effect.

listed proxy servers to the route headers of the SIP REGISTER  
request.  
Outbound Proxy Enter the outbound SIP proxy server’s IP address or name in the  
Outbound Proxy field. If there are multiple SIP proxies, separate the  
addresses by a comma. Also note that on the SIP Settings page  
there’s an option to allow strict routing. If that option is set and you  
have a SIP proxy that is configured for loose routing, add the “;lr”  
designation after the proxy’s address, for example,  
“10.134.129.101;lr”.  
ID  
ID is the phone’s SIP ID used for SIP registration. If this field is left  
blank, the Username field will be used as the ID.  
Display Name is the string that is shown at the far side when you  
make outbound calls. If you do not provide a Display Name, the  
Username will be used. Please note that your IP PBX might  
override the Display name sent by the FLX and replace it with  
names configured in the PBX.

SIP Settings  
Use the SIP Settings page to configure settings related to SIP sessions, as shown in the  
illustration below. After changing any of these settings, the phone must be restarted for  
the changes to take effect.  
SIP Settings  
Use SIP session Specify the preference for using SIP session keep-alive timers.  
timers  
During a SIP session, if SIP session timers are active, the SIP User  
Agent (UA) periodically sends INVITE or UPDATE requests (also  
called refresh requests) to keep the SIP session alive. The interval  
and use of the keep-alive is determined at call negotiation. If one of  
the UAs in a call does not receive the refresh request within the  
expiration timeout period, it will terminate the session.  
The available options in FLX are:  
Inactive – Session Timers will not be used in any session, except if  
explicitly required in the remote request.  
Optional – Session Timers will be used in all sessions whenever the  
remote supports and uses it.  
Required – Session Timers support will be a requirement for the  
remote to be able to establish a session.  
Always – Session Timers will always be used in all sessions,  
regardless of whether or not the remote supports or uses them. This  
option is the FLX default.  
Session timers  
The expiration period is the interval at which the phone will consider  
expiration period the SIP session timed out if it does not receive a refresh message  
from the remote phone. It is measured in seconds; the default is  
1800. At call negotiation, the nodes will negotiate the expiration

period to be used for the session.  
Session timers  
minimum  
This is the minimum session timer expiration period that FLX will  
accept when negotiating the expiration period with the remote  
expiration period phone. It is measured in seconds; the default is 90.  
Require reliable  
SIP provisional  
response  
Select this option to implement reliable SIP provisional responses.  
By default the setting is unchecked. SIP is a request-response type  
of protocol with two types of responses: provisional and final. Final  
responses are sent reliably, using an ACK to ensure receipt.  
Provisional responses by default are not sent reliably and do not  
require an ACK; however, in some cases, such as for PSTN  
interoperability support, reliability of provisional types of responses  
is needed. Choose this option to add the PRACK (provisional ACK)  
message support for reliability.  
Enable SIP  
traversal behind  
symmetric NAT  
This option may be used when the phone is behind a symmetric  
NAT (Network Address Translation). When enabled, FLX will keep  
track of the public IP address from the response of the REGISTER  
request. If it detects that the address has changed, it will unregister  
the current Contact, update the Contact with the transport address  
obtained from the Via header, and register a new Contact to the SIP  
registrar. This option will also update the public name of the UDP  
transport if STUN is configured.  
Suppress SIP  
event  
subscription  
When transferring a SIP call, the SIP REFER process automatically  
establishes a temporary event subscription to notify the party  
initiating the transfer about the receiver’s status in handling the  
when transferring REFER. In some cases these event subscriptions and notifications  
calls  
are not needed, such as when forking is not used. Enable this option  
to suppress the automatic event subscriptions when transferring  
calls. The option is disabled by default.  
Allow strict  
routing  
By default, proxies specified on the SIP Registration page will be  
configured as loose-routing proxies. The loose-routing designation  
(“;lr”) will be automatically appended to each proxy address when  
the proxy is added to the SIP Route header. Older proxies may be  
strict-routing (see IETF RFC 2543), not supporting loose routing  
(see IETF RFC 3261). Enable this option if you are using strict-  
routing proxies. If this option is enabled and you are specifying one  
or more loose-routing proxies in the SIP Registration page’s  
Outbound Proxy field, then you must manually add the “;lr” suffix to  
each loose-routing proxy address. For example, “10.134.123.101;lr”.  
The SIP protocol specifies that header field names can be in the full  
name form or in the abbreviated form. Abbreviated form is useful  
when messages might be too large to be carried on the available  
transport, for example when exceeding UDP’s Maximum  
Minimize SIP  
message size  
Transmission Unit (MTU). Enable this option to encode SIP headers  
in their short forms to reduce size. By default, the option is not  
enabled and SIP headers in outgoing messages will be encoded in  
their full names. (See SIP protocol standard, IETF RFC 3261.)

DTMF Signaling  
Method  
Select the signaling method for transmitting DTFM tones, either via  
RTP (RFC2833) or SIP INFO messages. The default is RTP.  
Transport  
Use the web interface’s Transport page to manage transport and Network Address  
Translation (NAT) settings, and to enable or disable Quality of Service (QoS). The  
illustration below shows the Transport page. After changing any of these settings, the  
phone must be restarted for the changes to take effect.

Transport Settings  
Use SRTP  
Use this setting to control Secure Real-time Transport Protocol  
(SRTP) usage. These are the available options:  
Disabled – Do not use SRTP; always use RTP. This is the default  
setting.  
Optional – Use the optional disposition for SRTP in SDP. If the  
remote end supports SRTP, then use SRTP; otherwise, use RTP.  
Mandatory – Force use of SRTP. If the remote end does not support  
SRTP, the call does not connect.  
Optional by duplicating media offer – Use duplicated media, both  
secured and unsecured versions, in the SDP offer.  
This is the base port number for RTP. The default is 4000. RTP is  
originated and received on even port numbers, and the associated  
RTCP uses the next higher odd port number. The range is 0 to  
65535.  
Start RTP Port  
TCP/UDP  
Selection  
Select the transport that will be enabled for SIP messages. The  
options are:  
Both TCP and UDP, TCP Only, and UDP Only. The default is Both  
TCP and UDP. Note that UDP will be used if it is available.  
Specify the local port for SIP transport. The default is 5060 for UDP  
and TCP. (Both use the same port.) The range is 0 to 65535.  
Optional. If specified, use this IP address (or hostname) as the  
advertised SIP and RTP address of this transport (the public  
address). The IP address does not have to correspond with one of  
the local host network interfaces; it may be the public IP address of  
a NAT router where port mappings have been configured for the  
phone application.  
Local TCP/UDP

IP Address (SIP  
and RTP  
address)  
Bound IP  
Address  
Optional. Bind the SIP and media transports to the specified IP  
address. The IP address must be an IP address of one of the host  
network interfaces.  
NAT Settings  
STUN Server  
Optional. Specify the STUN (Session Traversal Utilities for NAT)  
server to use to determine if the phone is behind a NAT, the type of  
NAT, and the public address of the phone. The field can contain a  
comma separated list of servers. Each server can be a domain  
name, host name, or IP address, and it may contain an optional port  
number. (For STUN see IETF RFC 5389.)  
Use ICE  
Check this option to use the ICE (Interactive Connectivity  
Establishment) protocol for NAT traversal. This option is checked by  
default. ICE takes advantage of STUN and TURN to identify  
candidates (IP addresses and ports) for communication, evaluating  
and prioritizing the candidate pairs to select the best route.  
Expensive candidates, such as using a media relay, are selected  
only as a last resort. (For ICE see IETF RFC 5245.)  
ICE Nomination  
Method  
When using ICE, select the preferred ICE Nomination Method. To  
validate candidate pairs (IP addresses and ports for the local and  
61

remote nodes), FLX sends STUN binding requests as part of the  
media connectivity tests. When a candidate is nominated for use, a  
STUN binding request is sent with a flag indicating that the  
candidate pair is nominated. There are two nomination methods that  
can be used:  
Regular – For Regular Nomination, FLX validates candidate pairs  
with initial STUN binding requests, and then selects a valid  
candidate pair by sending another STUN binding request with a flag  
indicating that the pair is nominated.  
Aggressive – For Aggressive Nomination, FLX doesn’t wait to set  
the nominated flag in a second STUN binding request, but rather  
sets the flag in the STUN binding requests for all of the candidate  
pairs. The ICE processing completes when the first pair successfully  
passes connectivity checks. The aggressive method is faster but  
does not always result in the optimal path being selected. This is the  
default method.  
Maximum  
number of ICE  
host candidates  
An ICE host candidate is an actual local transport address in the  
host. Host transport addresses are obtained by binding to attached  
network interfaces. These interfaces include both physical interfaces  
and virtual interfaces such as VPN. This option specifies the  
maximum number of local ICE host candidates that may be used in  
evaluating candidate pairs when determining the best route. The  
default value is -1 or an empty field, which indicates that there is no  
maximum.  
Disable RTCP  
component in  
ICE  
Select this option to disable the RTCP component in ICE. The  
option is unchecked by default.  
Enable TURN  
relay with ICE  
Select this option to enable the use of a TURN (Traversal Using  
Relay NAT) relay when using ICE. A TURN relay is a media relay  
server residing on the public internet which can relay media data  
packet between clients. TURN relays are used when other preferred  
mechanisms are not available, such as STUN or direct connectivity.  
The option is unchecked by default. If TURN is enabled, the TURN  
settings below (server, username and password) must also be  
specified.  
TURN Server  
Specify the TURN server domain name or hostname. The format is  
either "DOMAIN:PORT" or "HOST:PORT"  
TURN Username Specify the username to authenticate against the TURN server.  
TURN Password Specify the password to authenticate against the TURN server.  
Use TCP  
Use TCP to communicate with the TURN server rather than UDP.  
This option is unchecked by default.

Differentiated Services Code Point (DSCP) in the IP header is set to  
24 (0x18). For layer 2, IEEE 802.1p tagging is supported. This  
option is unchecked by default.  
Media Settings  
Use the Media page to specify the preferred audio codecs and other audio stream  
processing preferences as shown in the illustration below. After changing any of these  
settings, the phone must be restarted for the changes to take effect.  
Media Settings  
Codec 1, 2, 3, 4 Use the four codec fields to specify the preferred audio codecs to  
use, listed in priority order. The supported codecs are: G.722,  
G.711 µ-law (PCMU), G.711 α-law (PCMA), and G.726-32kbps. If  
fewer than four codecs are desired, choose “Disabled” for the  
unused codec options. Please note that at least one Codec has to  
be provided as Codec 1 does not offer the option “Disabled”. The  
default precedence order is as shown in the list above.  
Audio Quality  
The Audio Quality setting determines which audio resampling  
method to use. A higher number uses a more sophisticated  
resampling method (ranging from a large filter to smaller filters down  
to a linear method). More sophisticated resampling requires more  
CPU processing, but delivers better audio quality. Audio Quality can  
be set to values between 1 and 10, with 6 being the default.  
The ptime (packetization interval) value for a codec determines the  
length of time in milliseconds represented by the media in an RTP  
packet which is used to transmit audio traffic. The valid range is 10-  
1000. Leave the field blank to use the default value. For all of the  
codecs supported by FLX, the default ptime value is 20 ms/packet.

Disable silence  
detector/voice  
activity detector  
Select this option to disable silence detector/voice activity detector  
(VAD). VAD is a technique used in audio processing to detect the  
presence or absence of human speech. Disabling VAD is  
sometimes useful to work around NAT problems. This option is  
unchecked by default.  
Jitter buffer  
maximum delay  
Specify the jitter buffer maximum delay in milliseconds. Leave the  
field empty or specify -1 to use the default. The FLX default is 500  
ms.  
Call Settings  
From the Call Settings page you can choose to automatically answer calls, set the  
maximum call duration, and enable or disable the FLX Handset’s message waiting  
indicator. The figure below shows the Call Settings page. After changing any of these  
settings, the phone must be restarted for the changes to take effect.  
Call Settings  
Auto-answer  
This option allows to automatically answer calls even if not  
physically at the location where the phone is located. We  
recommend enabling this feature only for test purposes.  
Enable Auto-answer to automatically answer incoming calls. If the  
phone is set to Do Not Disturb or if there are no available lines, the  
Forward rules will apply. If there are no Forward rules specified, the  
incoming call will be sent to voice mail. If voice mail is not  
supported, the call will be rejected.  
Maximum call  
duration  
Specify the maximum call duration in seconds. When the call  
duration reaches the maximum duration, the call will be  
automatically terminated. An empty field indicates no maximum.  
Enable message Select this option to display the message waiting indicator (MWI) on  
waiting indication the FLX handset and to enable message waiting notifications from  
the PBX. The PBX must be configures to support voice mail for the  
registered user in order for this feature to work properly.

Advanced Audio Settings  
Use the Advanced Audio Settings page to specify microphone mute behavior, AUX  
audio in and out settings, and Acoustic Echo Cancellation (AEC) settings. The  
illustration below shows this page. The settings and options on this page reflect the  
same settings as can be done on the handset, allowing remotely setting and managing  
the phone behavior.  
Any changes on this page take effect as soon as the settings are saved; it is not  
necessary to restart the phone, but it is necessary to press “Save” for the change to be  
taken into the phone.  
Advanced Audio Settings  
All Mic Mute  
If “All Mic Mute” is On, all active microphones are affected when a  
mute button is pressed. If one or more active microphones are  
outside the Charger Base, pressing the mute button will change the  
mute status on all microphones outside of the Charger Base.  
Microphones in the Charger Base will not be affected and will stay  
muted at all times. If all microphones are in the Charger Base,  
pressing the mute button will change the mute status of all  
microphones in the Charger Base. The default for “All Mic Mute’” is  
Off.  
Start Mute  
The “Start Unmute” option specifies that microphones will be  
unmuted when taken out of the Charger. The default value is On.

RF Setting  
Use the RF Setting page to set the Radio Frequency (RF) signal strength of the base  
station and microphones. There are three RF Power settings: High, Medium, and Low.  
The default is High. Low or Medium can be selected to reduce the signal strength.  
Lower signal strength reduces the maximum distance between the base station and any  
of the wireless devices. A lower setting might be desirable in environments where more  
wireless DECT traffic is encountered.  
The illustration below shows the RF Setting page. It is not necessary to restart the  
phone after changing the RF Power setting, but it is necessary to press “Save” for the  
change to be taken into the phone.  
Access Control

password protected for all pages. It is restricted to Administrator  
use. If disabled, any web-access is rejected. Once web access is  
disabled, it can only be enabled again by an administrator from the  
handset. The default setting is On  
Importing and Exporting Configuration Settings  
Through the web interface you can import and export FLX configuration settings. These  
features are particularly useful if you are installing several FLX phones and want them  
all to use the same base set of configuration values.  
A common procedure would be to configure one FLX phone as desired, ensure that it is  
working properly in your environment, and then export the configuration settings for that  
phone. Then, you would use that configuration file as a starting point for the other  
phones, importing that file into each of the other phones.  
The export process creates a single XML file that includes all the core settings,  
excluding the following:  
Static IP Address  
SIP ID  
Display Name  
Username  
Password  
Below is an illustration of the Import/Export page.

Download from Www.Somanuals.com. All Manuals Search And Download.  
To export FLX configuration settings, click the Export button. A File Download window  
will appear prompting you to open or save the file as shown below. Click the “Save”  
button to save the file to the desired location.  
To import a configuration file, open a web session and login to the target phone to be  
configured, and select the Administrator > Import/Export page. Use the File to Upload  
field’s Browse button to navigate to the previously saved configuration file, select the file  
in the file browser, and then click the Import button.  
After importing the settings, you must minimally set the target phone-specific settings  
that were not uploaded with the import.  
Use the web interface to browse to the Network page and specify either DHCP or the  
Static IP-related settings as described in this manual. Also, browse to the SIP  
Registration page and specify the registration settings for the phone being configured.  
After importing, you must restart the phone for the changes to take effect.  
Downloading the System Log Package  
If you have problems with the FLX conference phone or questions about its operation,  
the support staff may request that you download the FLX system log package for their  
review.  
Select the Administrator > System Log page, and click the Retrieve button to begin the  
download process as shown in the picture.  
68  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Your web browser should indicate the download progress. When the download is  
complete, you will be prompted to save the compressed configuration file. The file name  
will include the IP address of the FLX and a date and time stamp, for example, log-  
10.134.123.101-120131-210112.tar.gz.  
You should be able to email the compressed file as instructed by the support staff.  
The support staff may also ask you to select the option to Enable Verbose SIP Logging.  
Selecting this option will cause the system to log more of the internal operations and  
network traffic useful for isolating problems. However, the additional logging can  
degrade performance.  
NOTE: Use this setting only when instructed by your support  
staff, and uncheck this option after you have retrieved the  
system log package.  
Call Status  
The Call Status page displays summary call statistics while in an active call. If there is  
no active call, the page will show a “No active call” message. If in a call, the page will  
show stats similar to those below. Click the Refresh button to manually refresh the  
page. The page does not update automatically. You can select, copy and paste the

Battery Exchange  
The rechargeable batteries in the different FLX components can all be exchanged.  
Please note that only Revolabs approved batteries should be used for the replacement.  
The following sections explain how to change the batteries in the different components.  
We recommend charging any component for 8 hours after exchanging the battery.  
Microphones  
To exchange a microphone battery push the bottom part of the back cover slightly down  
towards the charger port and then lift it as shown in the illustration below.  
Carefully take the battery out of the plastic cover. Put the new battery into the back  
cover as shown in the figure below. Press on the battery until it snaps into the back of  
the microphone housing.  
Slide the back of the microphone back in place. Place the microphone back into the  
charger base. The LED should go on indicating the charge status of the microphone.  
Dialer  
The battery in the dialer can be exchanged after the dialer’s back was  
opened. The back of the dialer opens if pressure is applied, pushing the  
back up away from the charger port and lift it, as shown in the picture.

Take the current battery out of the handset as shown, and replace it with  
the new battery. Please ensure that the connectors on the battery are  
lined up with the connectors inside the dialer.  
Speaker  
To change the rechargeable battery in the FLX speaker you will  
need to use a screwdriver to loosen the screw on the bottom of  
the speaker.  
Once the screw is loose, the bottom door of the speaker will  
open, revealing the rechargeable battery pack. Carefully take  
this battery pack out of the speaker enclosure, unplugging the  
wire.  
Plug the new replaceable battery into the connector, and place it  
into the speaker. Close the door, and re-tighten the screw.

Troubleshooting  
Warning Messages  
Speaker / Microphone Link Lost  
If a FLX Microphone or FLX Speaker loses connection to the FLX2 Base Station, the  
LED indicator will begin flashing a sequence of red – yellow - green - yellow and start  
emitting a beeping notification. To reconnect the Microphone or Speaker move it back  
into range of the Base Station.  
Speaker/Microphone Low Battery  
If a FLX Microphone or FLX Speaker begins to experience a low battery, the LED  
indicator will begin to flash a green - yellow (unmuted) or red - yellow (muted)  
sequence. It will also start to emit an audio signal. When this LED and sound sequence  
begins, the battery has roughly 5% battery power remaining and should be returned to  
the Charger Base.  
Speaker/Microphone Off  
If the FLX Microphone or FLX Speaker suddenly turns off, it is the result of two possible  
causes.  
1. The battery has completely depleted and should be returned to the charger until  
it is fully charged again.  
2. The Microphone or Speaker lost connection with the Base Station for more than  
10 minutes and therefore shut down. It should be returned into reach of the Base  
Station and switched on again to be reactivated.  
Dialer Low Battery  
When the Dialer experiences a low battery it will display a ‘low battery’ notification on  
the screen. The Dialer should be returned to the charger until the battery status on the  
home screen shows a full charge.  
Dialer Link Lost  
If the FLX Dialer loses connection to the FLX2 Base Station it will display a ‘connection  
lost’ notification on the screen and starts emitting a warning sound. The Dialer should  
be moved back into range of the Base Station at which point it will reconnect  
automatically.  
Base Power Lost  
If the FLX2 Base Station loses power, it will disconnect all telephone calls, analog audio  
inputs/outputs and will disconnect from the FLX Dialer, Speaker, and Microphones.  
Check to make sure that the power adapter is still connected to the FLX2 Base Station.  
Once the FLX2 Base Station is powered back on, the Dialer, Speaker and Microphones  
will reconnect automatically.  
Microphone, Speaker, or Dialer not connecting to Base Station  
If any of the components of the FLX2 Conference Phone indicate that they are  
searching for the Base Station, or lost the connection to the Base Station, please follow  
these steps:  
1. Is the Base Station powered up – the Status LED on the back of the Base Station  
should have green double flashes about every second. If not, please power up  
74  
Download from Www.Somanuals.com. All Manuals Search And Download.  
the Base Station. All components should automatically connect to the Base  
Station after a few seconds.  
2. The Base Station is powered up, but the Status LED indicates a fault has  
happened by missing every fifth green double flash. Power down and power up  
the Base Station. All components should reconnect to the Base Station after a  
few seconds. The fault message in the Base Station will continue (every fifth  
double flash is skipped) – this just shows that a fault has happened in the past  
and can be ignored. If the components still do not connect to the base please  
contact Revolabs Support.  
3. Are the Dialer, Microphone, and Speaker out of reach of the Base Station?  
Please bring the components closer to the Base Station to see whether this  
resolves the issue.  
4. Power down the Base Station, the Microphones, the Dialer, and the Speaker.  
Now power up the Base Station. Once the Base Station is powered up (double  
green flashes of the Status LED), power up the Dialer, and then the Microphones  
and the Speaker. The components should now connect to the Base Station.  
5. If the components still do not connect to the Base Station, please re-pair the  
components that have not connected to the Base Station, beginning with the  
Dialer. Pair of components to the Base Station is explained on page 42.  
6. If the components still do not connect to the Base Station, please contact  
Revolabs support.  
Microphone, Speaker, or Dialer not paired with Base Station  
Please follow the descriptions on page 42 on how to pair the different components with  
the Base Station.

GPL LICENSED SOFTWARE  
The following GPL licensed software is used in this product and is subject to the GNU  
General Public License version 2 (GPLv2) License  
Agreements included as part of this documentation:  
uClinux 2.6.26  
BusyBox 1.2.2  
Source code for this software can be obtained by contacting Revolabs at  
GNU GENERAL PUBLIC LICENSE  
Version 2, June 1991  
Copyright (C) 1989, 1991 Free Software Foundation, Inc.  
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA  
Everyone is permitted to copy and distribute verbatim copies  
of this license document, but changing it is not allowed.  
Preamble  
The licenses for most software are designed to take away your freedom to share and  
change it. By contrast, the GNU General Public License is intended to guarantee your  
freedom to share and change free software--to make sure the software is free for all its  
users. This General Public License applies to most of the Free Software Foundation's  
software and to any other program whose authors commit to using it. (Some other Free  
Software Foundation software is covered by the GNU Lesser General Public License  
instead.) You can apply it to your programs, too.  
When we speak of free software, we are referring to freedom, not price. Our General  
Public Licenses are designed to make sure that you have the freedom to distribute  
copies of free software (and charge for this service if you wish), that you receive source  
code or can get it if you want it, that you can change the software or use pieces of it in  
new free programs; and that you know you can do these things.  
To protect your rights, we need to make restrictions that forbid anyone to deny you  
these rights or to ask you to surrender the rights. These restrictions translate to certain  
responsibilities for you if you distribute copies of the software, or if you modify it.  
For example, if you distribute copies of such a program, whether gratis or for a fee, you  
must give the recipients all the rights that you have. You must make sure that they, too,  
receive or can get the source code. And you must show them these terms so they know  
their rights.  
We protect your rights with two steps: (1) copyright the software, and (2) offer you this  
license which gives you legal permission to copy, distribute and/or modify the software.  
Also, for each author's protection and ours, we want to make certain that everyone  
understands that there is no warranty for this free software. If the software is modified  
by someone else and passed on, we want its recipients to know that what they have is  
not the original, so that any problems introduced by others will not reflect on the original  
authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid  
the danger that redistributors of a free program will individually obtain patent licenses, in  
effect making the program proprietary. To prevent this, we have made it clear that any  
patent must be licensed for everyone's free use or not licensed at all.  
The precise terms and conditions for copying, distribution and modification follow.  
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION  
0. This License applies to any program or other work which contains a notice placed by  
the copyright holder saying it may be distributed under the terms of this General Public  
License. The "Program", below, refers to any such program or work, and a "work based  
on the Program" means either the Program or any derivative work under copyright law:  
that is to say, a work containing the Program or a portion of it, either verbatim or with  
modifications and/or translated into another language. (Hereinafter, translation is  
included without limitation in the term "modification".) Each licensee is addressed as  
"you".  
Activities other than copying, distribution and modification are not covered by this  
License; they are outside its scope. The act of running the Program is not restricted,  
and the output from the Program is covered only if its contents constitute a work based  
on the Program (independent of having been made by running the Program). Whether  
that is true depends on what the Program does.  
1. You may copy and distribute verbatim copies of the Program's source code as you  
receive it, in any medium, provided that you conspicuously and appropriately publish on  
each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the  
notices that refer to this License and to the absence of any warranty; and give any other  
recipients of the Program a copy of this License along with the Program.  
You may charge a fee for the physical act of transferring a copy, and you may at your  
option offer warranty protection in exchange for a fee.  
2. You may modify your copy or copies of the Program or any portion of it, thus forming  
a work based on the Program, and copy and distribute such modifications or work under  
the terms of Section 1 above, provided that you also meet all of these conditions:  
a) You must cause the modified files to carry prominent notices stating that you  
changed the files and the date of any change.  
b) You must cause any work that you distribute or publish, that in whole or in part  
contains or is derived from the Program or any part thereof, to be licensed as a  
whole at no charge to all third parties under the terms of this License.  
c) If the modified program normally reads commands interactively when run, you  
must cause it, when started running for such interactive use in the most ordinary  
way, to print or display an announcement including an appropriate copyright  
notice and a notice that there is no warranty (or else, saying that you provide a  
warranty) and that users may redistribute the program under these conditions,  
and telling the user how to view a copy of this License. (Exception: if the Program  
86  
Download from Www.Somanuals.com. All Manuals Search And Download.  
itself is interactive but does not normally print such an announcement, your work  
based on the Program is not required to print an announcement.)  
These requirements apply to the modified work as a whole. If identifiable sections of  
that work are not derived from the Program, and can be reasonably considered  
independent and separate works in themselves, then this License, and its terms, do not  
apply to those sections when you distribute them as separate works. But when you  
distribute the same sections as part of a whole which is a work based on the Program,  
the distribution of the whole must be on the terms of this License, whose permissions  
for other licensees extend to the entire whole, and thus to each and every part  
regardless of who wrote it.  
Thus, it is not the intent of this section to claim rights or contest your rights to work  
written entirely by you; rather, the intent is to exercise the right to control the distribution  
of derivative or collective works based on the Program.  
In addition, mere aggregation of another work not based on the Program with the  
Program (or with a work based on the Program) on a volume of a storage or distribution  
medium does not bring the other work under the scope of this License.  
3. You may copy and distribute the Program (or a work based on it, under Section 2) in  
object code or executable form under the terms of Sections 1 and 2 above provided that  
you also do one of the following:  
a) Accompany it with the complete corresponding machine-readable source  
code, which must be distributed under the terms of Sections 1 and 2 above on a  
medium customarily used for software interchange; or,  
b) Accompany it with a written offer, valid for at least three years, to give any  
third party, for a charge no more than your cost of physically performing source  
distribution, a complete machine-readable copy of the corresponding source  
code, to be distributed under the terms of Sections 1 and 2 above on a medium  
customarily used for software interchange; or,  
c) Accompany it with the information you received as to the offer to distribute  
corresponding source code. (This alternative is allowed only for noncommercial  
distribution and only if you received the program in object code or executable  
form with such an offer, in accord with Subsection b above.)  
The source code for a work means the preferred form of the work for making  
modifications to it.  
For an executable work, complete source code means all the source code for all  
modules it contains, plus any associated interface definition files, plus the scripts used  
to control compilation and installation of the executable. However, as a special  
exception, the source code distributed need not include anything that is normally  
distributed (in either source or binary form) with the major components (compiler,  
kernel, and so on) of the operating system on which the executable runs, unless that  
component itself accompanies the executable.  
87

If distribution of executable or object code is made by offering access to copy from a  
designated place, then offering equivalent access to copy the source code from the  
same place counts as distribution of the source code, even though third parties are not  
compelled to copy the source along with the object code.  
4. You may not copy, modify, sublicense, or distribute the Program except as expressly  
provided under this License. Any attempt otherwise to copy, modify, sublicense or  
distribute the Program is void, and will automatically terminate your rights under this  
License. However, parties who have received copies, or rights, from you under this  
License will not have their licenses terminated so long as such parties remain in full  
compliance.  
5. You are not required to accept this License, since you have not signed it. However,  
nothing else grants you permission to modify or distribute the Program or its derivative  
works. These actions are prohibited by law if you do not accept this License. Therefore,  
by modifying or distributing the Program (or any work based on the Program), you  
indicate your acceptance of this License to do so, and all its terms and conditions for  
copying, distributing or modifying the Program or works based on it.  
6. Each time you redistribute the Program (or any work based on the Program), the  
recipient automatically receives a license from the original licensor to copy, distribute or  
modify the Program subject to these terms and conditions. You may not impose any  
further restrictions on the recipients' exercise of the rights granted herein. You are not  
responsible for enforcing compliance by third parties to this License.  
7. If, as a consequence of a court judgment or allegation of patent infringement or for  
any other reason (not limited to patent issues), conditions are imposed on you (whether  
by court order, agreement or otherwise) that contradict the conditions of this License,  
they do not excuse you from the conditions of this License. If you cannot distribute so as  
to satisfy simultaneously your obligations under this License and any other pertinent  
obligations, then as a consequence you may not distribute the Program at all. For  
example, if a patent license would not permit royalty-free redistribution of the Program  
by all those who receive copies directly or indirectly through you, then the only way you  
could satisfy both it and this License would be to refrain entirely from distribution of the  
Program.  
If any portion of this section is held invalid or unenforceable under any particular  
circumstance, the balance of the section is intended to apply and the section as a whole  
is intended to apply in other circumstances.  
It is not the purpose of this section to induce you to infringe any patents or other  
property right claims or to contest validity of any such claims; this section has the sole  
purpose of protecting the integrity of the free software distribution system, which is  
implemented by public license practices. Many people have made generous  
contributions to the wide range of software distributed through that system in reliance on  
88  
Download from Www.Somanuals.com. All Manuals Search And Download.  
consistent application of that system; it is up to the author/donor to decide if he or she is  
willing to distribute software through any other system and a licensee cannot impose  
that choice.  
This section is intended to make thoroughly clear what is believed to be a consequence  
of the rest of this License.  
8. If the distribution and/or use of the Program is restricted in certain countries either by  
patents or by copyrighted interfaces, the original copyright holder who places the  
Program under this License may add an explicit geographical distribution limitation  
excluding those countries, so that distribution is permitted only in or among countries  
not thus excluded. In such case, this License incorporates the limitation as if written in  
the body of this License.  
9. The Free Software Foundation may publish revised and/or new versions of the  
General Public License from time to time. Such new versions will be similar in spirit to  
the present version, but may differ in detail to address new problems or concerns.  
Each version is given a distinguishing version number. If the Program specifies a  
version number of this License which applies to it and "any later version", you have the  
option of following the terms and conditions either of that version or of any later version  
published by the Free Software Foundation. If the Program does not specify a version  
number of this License, you may choose any version ever published by the Free  
Software Foundation.  
10. If you wish to incorporate parts of the Program into other free programs whose  
distribution conditions are different, write to the author to ask for permission. For  
software which is copyrighted by the Free Software Foundation, write to the Free  
Software Foundation; we sometimes make exceptions for this. Our decision will be  
guided by the two goals of preserving the free status of all derivatives of our free  
software and of promoting the sharing and reuse of software generally.  
NO WARRANTY  
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO  
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE  
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT  
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT  
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT  
NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND  
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY  
AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM  
PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,  
REPAIR OR CORRECTION.  
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN  
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY  
MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE  
89

LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,  
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR  
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF  
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY  
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH  
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN  
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
