4.3 Making and Answering Phone Calls  
4.3.1 Handset, Speakerphone and Headset Mode  
Handset can be switched between either Speaker or Headset. However, whenever the Headset is  
plugged in, Speaker will be switched to Headset.  
To Switch between Handset and Speaker/Headset, simply press the Hook Flash in the Handset cradle  
or press the SPEAKER button in the phone.  
4.3.2 Multiple SIP Accounts and Lines  
GXV-3000 can support up to 3 independent SIP accounts. Each account is capable of independent SIP  
server, user and NAT settings among others. Each of the 3 LINE buttons (LINE1-LINE3) is “virtually”  
mapped to each SIP account. In off hook state, when user chooses an idle line, the name of the  
account (as configured in the web interface) will be displayed in the LCD while a dial tone is being  
played out. For example, if the 3 SIP accounts are named FWD (FreeWorldDialup), BroadVoice and  
Asterisk PBX respectively and they are all active and registered. When LINE1 is pressed, user will  
hear dial tone and see “FWD”. When LINE2 is pressed, user will hear dial tone and see “BroadVoice”.  
When LINE3 is pressed, user will hear dial tone and see “Asterisk PBX”.  
For outgoing calls, GXV-3000 will pick up the LINE pressed, which the LED will be lit up in solid red  
color. User can switch the dialing account before dialing any digits by pressing the same LINE button  
one or more times. If user continues to press one LINE, the selected account will circulate among the  
registered accounts. For example, when LINE1 is pressed, LCD displays “FWD”. If LINE1 is pressed  
twice, LCD displays “BroadVoice” and the subsequent call will be made through SIP account 2.  
- 15 -  
GXV-3000 User Manual  
Grandstream Networks, Inc.  
For incoming calls, if an account is configured and registered, all incoming calls for that account will  
attempt to use its corresponding LINE if it is not in use. When the “virtually” mapped line is in use,  
GXV-3000 will flash the next available LINE (from Left to Right) in red color.  
A LINE is defined as “ACTIVE” when it is making or receiving a call, and its corresponding LINE  
LED is lit up in solid RED.  
4.3.3 Making Calls  
There are four ways to make phone calls:  
1. Make Handset/SPEAKER/Headset off hook, or press the available LINE key to select a SIP  
account, the corresponding LINE LED will light up in solid red. Enter the phone numbers and  
press the SEND key.  
2. Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the  
corresponding LINE LED will light up in solid red. Press the SEND button to redial the last  
number called.  
3. Press the OK to bring up the Main Menu, select Phone Book, browse phone book to the person  
you want to dial, press OK to select and OK again when Dial is selected. The call will dial out  
in SPEAKER mode. (Right now this only applies to primary a/c which is LINE 1)  
4. Paging/Intercom: This is ONLY valid if the SERVER/PBX support this feature and both  
phone and PBX (for example, Asterisk) are configured correctly:  
Make Handset/SPEAKER/Headset off hook, select the LINE key to related feature available  
account, then press OK key again to see LCD showing: LINEx: PAGE USING. Now input the  
phone number you want to Page/Intercom and press SEND key.  
NOTE:  
Once off hook and key pressed, the dialed number will be displayed on the LCD and the  
corresponding DTMF tone will be played out.  
If the “SEND” button is not pressed after the phone number pressed, the phone (by default) will  
wait for 4 seconds (no key entry timeout) before sending all digits out and initiating the call.  
4.3.4 Making Calls using IP Address  
Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy.  
VoIP calls can be made between two phones if  
Both phones have public IP addresses, or  
Both phones are on a same LAN using private or public IP addresses, or  
Both phones can be connected through a router using public or private IP addresses.  
- 16 -  
GXV-3000 User Manual  
Grandstream Networks, Inc.  
To make a direct IP calling, press “OK” button to bring up MAIN MENU, the select “Direct IP Call”  
in the MENU and press OK to select, then key in the 12-digit target IP address, press OK key again to  
call out.  
Examples:  
If the target IP address is 192.168.1.60 and port is 5062, like 192.168.1.60:5062, the key input to the  
Menu UI will be:  
192*168*1*60#5062  
followed by OK key to dial out, where “*” key represent “.” and “#” key represent “:”  
NOTE:  
When doing Direct IP calling, make sure the “Use Random Port” is configured as “NO”.  
Otherwise it will not work unless the phone is configured to listen to the special port you  
specified and also that port need to be inputted in the dialing digits.  
4.3.5 Receiving Calls  
There are three states when GXV-3000 receives a call:  
1. When receiving an initial call. Besides ringing with selected Ring Tone, the corresponding  
account LINE will flash in red, taking Handset/SPEAKER/Headset off hook will enable user to  
hear the calling party in Handset/SPEAKER/Headset.  
2. When receiving second or more incoming calls, besides playing stutter Call Waiting tone,  
GXV-3000 will pick up the corresponding account LINE or the next available LINE as  
described in section 4.3.2.  
3. When the related configuration is enabled for Paging/Intercom and the PBX (or Server) also  
supports this feature, the phone will beep once and automatically establish the call via  
SPEAKER.  
4.3.6 Call Hold  
While in conversation, pressing the “HOLD” button will put the other party on hold. User can resume  
the conversation by pressing the corresponding blinking LINE. User will also automatically put the  
current line on “HOLD” by pressing another available LINE for making or receiving other phone calls.  
4.3.7 Call Waiting and Switch between Calls  
GXV-3000 can switch to another line for making or answering calls and automatically put an  
ACTIVE call on Hold.  
- 17 -  
GXV-3000 User Manual  
Grandstream Networks, Inc.  
When receiving second or more incoming calls, besides playing a stutter Call Waiting tone, GXV-3000  
will pick up the corresponding account or the next available LINE as described in section 4.3.2.  
4.3.8 Call Transfer

1. Blind Transfer: When a LINE is “ACTIVE”, user will get a dial tone by pressing the “TRNF”  
button, then dial the number and press the “SEND” button, this will transfer the other party in  
the corresponding LINE to the dialed number.  
2. Attended Transfer: When in conversation with an “ACTIVE” LINE as defined in section 4.3.2,  
user shall press “TRNF” button, then press the intended blinking LINE that is on “HOLD”.  
If there is no LINE on HOLD, user will need to make a call and thus automatically puts the  
current ACTIVE LINE on HOLD.  
NOTE:  
Transferring calls across SIP domains needs to be supported by SIP service providers.  
4.3.9 3-Way Conferencing (Pending: Only work in Audio mode)  
GXV-3000 supports 3-way conferencing. With one LINE ACTIVE and another LINE on HOLD, press  
the CONF button then the LINE that is on HOLD will join the three parties together in a conference.

resume the conversation by pressing CONF or the original LINE button.  
If the conference holder wishes to end a conference, simply press HOLD, which breaks the conference  
and places both parties on hold. User can then talk to each individual party by selecting the  
corresponding LINE.  
4.3.10 Checking Message and Message Waiting Indication  
When GXV-3000 is on-hook, pressing the MSG button will trigger the phone to call the  
VoiceMail Server (VMS) configured for the primary account. If a line/account is selected first, it dials  
the VMS configured for that account.  
The MWI (Message Waiting Indicator) LED will flash in red color in three quarters of a second when  
voicemail server sends message waiting information to GXV-3000.

IP Address  
There are two modes under which the GXV-3000 can operate:  
If DHCP mode is enabled, then all the field values for the Static IP  
mode are not used (even though they are still saved in the Flash  
memory.) The GXV-3000 will acquire its IP address from the first  
DHCP server it discovers from the LAN it is connected. The DHCP  
option is reserved for NAT router mode (not ready yet)  
To use the PPPoE feature the PPPoE account settings need to be set.  
The GXV-3000 will attempt to establish a PPPoE session if any of  
the PPPoE fields is set.  
If Static IP mode is enabled, then the IP address, Subnet Mask,  
Default Router IP address, DNS Server 1 (primary), DNS Server 2  
(secondary) fields will need to be configured. These fields are set to  
zero by default.

GXV-3000 User Manual  
Grandstream Networks, Inc.  
Voice Frames This field contains the number of voice frames to be transmitted in a single Ethernet  
per TX  
packet (be advised the max. size of Ethernet packet is 1500 byte (or 120k bit) so  
user should be aware that there IS a limit there). When setting this value, the user  
should be aware of the requested packet time (ptime, used in SDP message) as a  
result of configuring this parameter. This parameter is associated with the first codec  
in the above codec Preference List or the actual used payload type negotiated  
between the 2 conversation parties at run time.  
e.g., if the first codec is configured as G723 and the “Voice Frames per TX” is set to  
be 2, then the “ptime” value in the SDP message of an INVITE request will be 60ms  
because each G723 voice frame contains 30ms of audio. Similarly, if this field is set  
to be 2 and if the first codec chosen is G729 or G711 or G726, then the “ptime”  
value in the SDP message of an INVITE request will be 20ms.  
If the configured voice frames per TX exceeds the maximum allowed value, the IP  
phone will use and save the maximum allowed value for the corresponding first  
codec choice. The maximum value for PCM is 10 (x10ms) frames; for G726, it is 20  
(x10ms) frames; for G723, it is 32 (x30ms) frames; for G729/G728, 64 (x10ms) and  
64 (x2.5ms) frames respectively.  
Please be very careful when massage those parameters. By adjust this, user also get  
jitter buffer changed accordingly. BT-100 phone has patent dynamic jitter buffer  
handling algorithm. The jitter buffer range from 20 ~ 200 ms.  
Incorrect setting will affect voice quality so do not touch the parameter if not  
understand and most of the case the default value will work in GS products.  
Please refer to the Codec FAQ in our website for more technical details:  
Video Frame Default value is 15 frames/second. User adjustable based on network condition.  
Rate  
Video bit rate Default value is 128 kbps. User adjustable based on network environment.

Screen  
When the received image size is bigger than the LCD resolution (QVGA), the  
GXV3000 can scale the image to fit the LCD or crop it.  
Layer 3 QoS  
This field defines the layer 3 QoS parameter which can be the value used for IP  
Precedence or Diff-Serv or MPLS. Default value is 48.  
Layer 2 QoS  
This contains the value used for layer 2 VLAN tag. Default setting is  
blank.  
No Key Entry Default is 4 seconds.  
Timeout  
Use # as  
This parameter allows users to configure the “#” key to be used as the “Send” (or  
Send Key  
“Dial”) key. If set to “Yes”, pressing this key will immediately trigger the sending of  
dialed string collected so far. In this case, this key is essentially equivalent to the  
“(Re)Dial” key. If set to “No”, this “#” key will then be included as part of the dial  
string to be sent out.

Local RTP  
port  
This parameter defines the local RTP-RTCP port pair the GXV-3000 will listen and  
transmit. It is the base RTP port for channel 0. When configured, channel 0 will use  
this port _value for RTP and the port_value+1 for its RTCP; channel 1 will use  
port_value+2 for RTP and port_value+3 for its RTCP. The default value is 5004.  
Use Random  
Port  
This parameter, when set to Yes, will force random generation of both the local SIP  
and RTP ports. This is usually necessary when multiple GXV-3000s are behind the  
same NAT.  
Keep-alive  
interval  
This parameter specifies how often the GXV-3000 sends a blank UDP packet to the  
SIP server in order to keep the “hole” on the NAT open. Default is 20 seconds.  
Use NAT IP  
NAT IP address used in SIP/SDP message. Default is blank.  
STUN Server IP address or Domain name of the STUN server.  
Firmware  
This radio button will enable GXV-3000 to download firmware or configuration file  
Upgrade and through either HTTP or local TFTP server. This is mutual exclusive choice.  
provisioning  
Via TFTP  
Server  
This is the IP address of the configured TFTP server. If selected and it is non-zero or  
not blank, the GXV-3000 will attempt to retrieve new configuration file or new code  
image from the specified TFTP server at boot time. It will make up to 3 attempts  
before timeout and then it will start the boot process using the existing code image in  
the Flash memory. If a TFTP server is configured and a new code image is retrieved,  
the new downloaded image will be verified and then saved into the Flash memory.  
Note: It is strongly recommended that user upgrade firmware locally in LAN  
environment if using TFTP to upgrade. Please do NOT interrupt the TFTP upgrade  
process (especially the power supply) as this will damage the device.  
Via HTTP  
Server  
The URL for the HTTP server used for firmware upgrade and configuration via  
HTTP. For example,  
Here “:6688” is the specific TCP port that the HTTP server is listening at, it can be  
omitted if using default port 80.  
Note: If Auto Upgrade is set to No, GXV-3000 will only do HTTP download once  
at boot up.  
Automatic  
Upgrade  
Default is Yes. Choose Yes to enable automatic HTTP upgrade and provisioning.  
In “Check for upgrade every” field, enter the number of minutes to enable the phone  
to check the HTTP server for firmware upgrade or configuration changes in the  
defined period of time.  
When set to No, the phone will only do HTTP upgrade and configuration check once  
at boot up. Used by ITSP. End user should NOT touch these parameters.

NAT Traversal  
This parameter defines whether the GXV-3000 NAT traversal mechanism will  
be activated or not. If activated (by choosing “Yes”) and a STUN server is also  
specified, then the GXV-3000 will behave according to the STUN client  
specification. Under this mode, the embedded STUN client inside the GXV-  
3000 will attempt to detect if and what type of firewall/NAT it is sitting behind  
through communication with the specified STUN server. If the detected NAT  
is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the GXV-3000 will  
attempt to use its mapped public IP address and port in all of its SIP and SDP  
messages. If the NAT Traversal field is set to “Yes” with no specified STUN  
server, the GXV-3000 will periodically (every 20 seconds or so) send a blank  
UDP packet (with no payload data) to the SIP server to keep the “hole” on the  
NAT open.  
Subscribe for MWI: Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting  
Indication will be sent periodically.  
Proxy-Require  
SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

(UPDATE, or re-INVITE. Once the session interval expires, if there is no  
refresh via a UPDATE or re-INVITE message, the session will be terminated.  
Session Expiration is the time (in seconds) at which the session is considered  
timed out, if no successful session refresh transaction occurs beforehand. The  
default value is 180 seconds.  
Min-SE  
The minimum session expiration (in seconds). The default value is 90  
seconds.  
Caller Request Timer If selecting “Yes” the phone will use session timer when it makes outbound  
calls if remote party supports session timer.

Callee Request Timer If selecting “Yes” the phone will use session timer when it receives inbound  
calls with session timer request.  
Force Timer  
If selecting “Yes” the phone will use session timer even if the remote party  
does not support this feature. Selecting “No” will allow the phone to enable  
session timer only when the remote party support this feature.  
To turn off Session Timer, select “No” for Caller Request Timer, Callee  
Request Timer, and Force Timer.  
UAC Specify

to use the phone as the refresher.  
Force INVITE  
Session Timer can be refreshed using INVITE method or UPDATE method.  
Select “Yes” to use INVITE method to refresh the session timer.  
Enable 100rel  
The use of the PRACK (Provisional Acknowledgment) method enables  
reliability to be offered to SIP provisional responses (1xx series). This is very  
important if PSTN internetworking is to be supported. A user’s wish to use  
reliable provisional responses is invoked by the 100rel tag which is appended  
to the value of the required header of initial signalling messages.  
Account Ring Tone  
Send Anonymous  
There are 4 different ring tone that are defined:  
System Ring Tone: when selected, all calls will ring with system ring  
tone.  
Customer Ring Tone 1 to 3: when selected, GXV-3000 will ONLY  
play this ring tone for all the incoming calls for this account.  
If this parameter is set to “Yes”, the “From” header in outgoing INVITE  
message will be set to anonymous, essentially blocking the Caller ID from  
displaying.  
Auto Answer  
When set to “Yes”, GXV-3000 will automatically switch to speaker when  
there is an incoming call.  
Preferred Vocoder  
The GXV-3000 supports up to 5 different Vocoder types including G.711 A-  
/U-law, GSM, G.723.1, G.729A/B.

5.3 Configuration through Central Provisioning Server  
Grandstream GXV-3000 can be automatically configured from a central provisioning system.  
When GXV-3000 boots up, it will send TFTP or HTTP request to download configuration file which is  
“cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the GXV-3000.  
The configuration file can be downloaded via TFTP or HTTP from the central server. A service  
provider or an enterprise with large deployment of GXV-3000 can easily manage the configuration and  
service provisioned for individual device from a central server remotely.  
Grandstream provides a licensed provisioning system called GAPS that can be used to support  
automated configuration of GXV-3000. GAPS (Grandstream Automated Provisioning System) uses  
enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to  
communicate with each individual GXV-3000 for firmware upgrade, remote reboot, etc.  
Grandstream provide GAPS (Grandstream Automated Provisioning System) service to VoIP service  
providers. It could be either simple redirection or with certain special provisioning settings. Initially  
upon booting up, Grandstream devices by default point to Grandstream provisioning server GAPS,  
based on the unique MAC address of each device, GAPS provision the devices with redirection  
settings so that they will be redirected to customer’s TFTP or HTTP server for further provisioning.  
Grandstream also provides GAPSLite software package which contains our NAT friendly TFTP server  
and a configuration tool to facilitate the task of generating device configuration files.  
The GAPSLite configuration tool is now free to end users. The tool and configuration templates can be  
For details on how GAPS works, please refer to the documentation of GAPS product or contact

Software Upgrade  
Software (or firmware) upgrade can be done via either TFTP or HTTP. The corresponding  
configuration settings are in the ADVANCED SETTINGS configuration page.  
6.1 Firmware Upgrade through TFTP/HTTP  
To upgrade via TFTP or HTTP, user needs to select TFTP or HTTP upgrade method. “Upgrade  
Server” needs to be set to a valid URL of a HTTP server. Server name can be in either FQDN or IP  
address format. Here are examples of some valid URL.  
e.g. firmware.mycompany.com:6688/Grandstream/1.0.0.18  
e.g. 168.75.215.189  
There are two ways to set up the Upgrade Server to upgrade firmware, namely through the Key Pad  
Menu or via the GXV-3000’s Web configuration interface. To configure the Upgrade Server via Key  
Pad Menu options, select “System Config” from the Main Menu, then select “Upgrade Preferences”.  
Under this sub Menu, user can edit Upgrade Server in either an IP address format or FQDN format.  
Choose “Save and use TFTP” or “Save and use HTTP” to select upgrade method. And select  
“Reboot” from the Main Menu to reboot the phone.  
To configure the Upgrade Server via the Web configuration interface, open up your web browser and  
enter the IP address of GXV-3000. Enter the admin password to get into the web configuration  
interface. In the ADVANCD SETTINGS page, enter the Upgrade Server’s IP address or FQDN in the  
“Upgrade Server” field. Select TFTP or HTTP upgrade method. Once these settings are entered, user  
needs to update the change by clicking the “Update” button. Then “Reboot” or power cycle the phone,  
the firmware files will be fetched upon booting up.  
If the configured upgrade server is found and a new code image is available, the GXV-3000 phone will  
attempt to retrieve the new image files by downloading them into the phone’s SRAM. During this  
stage, the GXV-3000 phone’s LCD will show firmware file downloading process. Upon verification of  
checksum, the new code image will be saved into the Flash. If firmware upgrade fails for any reason  
(e.g., TFTP/HTTP server is not responding, there are no code image files available for upgrade, or  
checksum test fails, etc), the GXV-3000 phone will stop the upgrading process and simply boot using  
the existing code image in the flash.  
Firmware upgrading may take as long as 45 minutes over Internet, or just 5 minutes on a controlled  
LAN. It is strongly recommended to conduct firmware upgrade in a controlled LAN environment  
whenever possible.  
For users who do not have local TFTP server, Grandstream provides a NAT-friendly TFTP server on  
the public Internet for users to download the latest firmware upgrade automatically. Please check the  
Services section of Grandstream’s Web site to obtain this TFTP server IP address:  
- 42 -  
GXV-3000 User Manual  
Grandstream Networks, Inc.  
Alternatively, user can download and install a free TFTP or HTTP server in his/her LAN to do  
firmware upgrading.  
A free Windows version TFTP server can be downloaded from:  
Our latest official release can be downloaded from:  
Unzip the file and put all of them under the root directory of the TFTP server. Put the PC running the  
TFTP server and the GXV-3000 phone in the same LAN segment. Please go to File -> Configure ->  
Security to change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the  
firmware upgrade. Start the TFTP server, in the phone’s web configuration page, configure  
the Firmware Server Path with the IP address of the PC, update the change and reboot the unit.  
User can also choose to download the free HTTP server from http://httpd.apache.org/ or just use  
Microsoft IIS web server  
NOTE:  
When GXV-3000 phone boots up, it will send TFTP or HTTP request to download  
configuration file “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the  
GXV-3000 phone. This file is for initial automatically provisioning purpose only, for normal  
TFTP or HTTP firmware upgrade, the following error messages in a TFTP or HTTP server log  
can be ignored.  
TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does not exist  
Configuration File Download  
NOTE:  
After flashing the firmware, a power cycle is required. Please power cycle the phone after  
the downloading process finished and when the LCD becomes pale or white.

6.2 Configuration File Download  
Grandstream SIP Device can be configured via Web Interface as well as via Configuration File  
through TFTP or HTTP. “Upgrade Server” is the TFTP or HTTP server path for configuration file. It  
needs to be set to a valid URL, either in FQDN or IP address format.  
A configuration parameter is associated with each particular field in the web configuration page. A  
parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric  
numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a  
detailed parameter list, please refer to the corresponding configuration template of the firmware.  
When Grandstream Device boots up or reboots, it will issue request for configuration file named  
“cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e.,  
“cfg000b820102ab”. The configuration file name should be in lower cases.  
6.3 Managing Firmware and Configuration File Download  
When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in  
minutes, default and minimum is 60 minutes) to have the devices periodically check with either  
Upgrade Server. This allows the device periodically check if there are any new changes need to be  
taken on a scheduled time. By defining different intervals in P193 for different devices, Server  
Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware  
or Provisioning Server load at any given time.

A suite of standards for multimedia conferences on traditional packet-switched networks.  
H.264, MPEG-4 Part 10, or AVC, for Advanced Video Coding, is a digital video codec  
standard which is noted for achieving very high data compression. It was written by the ITU-T  
Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts  
Group (MPEG) as the product of a collective partnership effort known as the Joint Video Team  
(JVT). The ITU-T H.264 standard and the ISO/IEC MPEG-4 Part 10 standard (formally,  
ISO/IEC 14496-10) are technically identical. The final drafting work on the first version of the  
standard was completed in May of 2003.

IP Telephony  
(Internet Protocol telephony, also known as Voice over IP Telephony) A general term for the  
technologies that use the Internet Protocol's packet-switched connections to exchange voice,  
fax, and other forms of information that have traditionally been carried over the dedicated  
circuit-switched connections of the public switched telephone network (PSTN). The basic steps  
involved in originating an IP Telephony call are conversion of the analog voice signal to digital  
format and compression/translation of the signal into Internet protocol (IP) packets for  
transmission over the Internet or other packet-switched networks; the process is reversed at the  
receiving end. The terms IP Telephony and Internet Telephony are often used to mean the  
same; however, they are not 100 per cent interchangeable, since Internet is only a subcase of  
packet-switched networks. For users who have free or fixed-price Internet access, IP Telephony  
software essentially provides free telephone calls anywhere in the world. However, the  
challenge of IP Telephony is maintaining the quality of service expected by subscribers.  
Session border controllers resolve this issue by providing quality assurance comparable to  
legacy telephone systems.  
IVR  
IVR is a software application that accepts a combination of voice telephone input and touch-  
tone keypad selection and provides appropriate responses in the form of voice, fax, callback, e-  
mail and perhaps other media.  
MTU

OBP/SBC  
Outbound Proxy or another name Session Border Controller. A device used in VoIP networks.  
OBP/SBCs are put into the signaling and media path between calling and called party. The  
OBP/SBC acts as if it was the called VoIP phone and places a second call to the called party.  
The effect of this behavior is that not only the signaling traffic, but also the media traffic  
(voice, video etc) crosses the OBP/SBC. Without an OBP/SBC, the media traffic travels  
directly between the VoIP phones. Private OBP/SBCs are used along with firewalls to enable  
VoIP calls to and from a protected enterprise network. Public VoIP service providers use  
OBP/SBCs to allow the use of VoIP protocols from private networks with internet connections  
using NAT.  
PPPoE  
PSTN  
Point-to-Point Protocol over Ethernet, is a network protocol for encapsulating PPP frames in  
Ethernet frames. It is used mainly with cable modem and DSL services.  
Public Switched Telephone Network  
i.e. the phone service we use for every ordinary phone call, or called POT (Plain Old

RTCP  
RTP  
Real-time Transport Control Protocol, defined in RFC 3550, a sister protocol of the Real-time  
Transport Protocol (RTP), It partners RTP in the delivery and packaging of multimedia data,  
but does not transport any data itself. It is used periodically to transmit control packets to  
participants in a streaming multimedia session. The primary function of RTCP is to provide  
feedback on the quality of service being provided by RTP.  
Real-time Transport Protocol defines a standardized packet format for delivering audio and  
video over the Internet. It was developed by the Audio-Video Transport Working Group of the  
IETF and first published in 1996 as RFC 1889  
SDP  
SIP  
Session Description Protocol, is a format for describing streaming media initialization  
parameters. It has been published by the IETF as RFC 2327.  
Session Initiation Protocol, An IP telephony signaling protocol developed by the IETF  
(RFC3261). SIP is a text-based protocol suitable for integrated voice-data applications. SIP is  
designed for voice transmission and uses fewer resources and is considerably less complex than  
H.323.  
All Grandstream products are SIP based  
STUN  
- 54 -  
GXV-3000 User Manual  
Grandstream Networks, Inc.  
Simple Traversal of UDP over NATs, is a network protocol allowing clients behind NAT (or  
multiple NATs) to find out its public address, the type of NAT it is behind and the internet side  
port associated by the NAT with a particular local port. This information is used to set up UDP  
communication between two hosts that are both behind NAT routers. The protocol is defined in  
RFC 3489. STUN will usually work well with non-symmetric NAT routers.  
TCP  
Transmission Control Protocol, is one of the core protocols of the Internet protocol suite. Using  
TCP, applications on networked hosts can create connections to one another, over which they  
can exchange data or packets. The protocol guarantees reliable and in-order delivery of sender  
to receiver data.  
TFTP  
UDP  
Trivial File Transfer Protocol, is a very simple file transfer protocol, with the functionality of a  
very basic form of FTP; It uses UDP (port 69) as its transport protocol.  
User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using  
UDP, programs on networked computers can send short messages known as datagrams to one  
another. UDP does not provide the reliability and ordering guarantees that TCP does;  
datagrams may arrive out of order or go missing without notice. However, as a result, UDP is  
faster and more efficient for many lightweight or time-sensitive purposes.  
VAD  
Voice Activity Detection or Voice Activity Detector is an algorithm used in speech processing  
wherein, the presence or absence of human speech is detected from the audio samples.  
VLAN  
VoIP  
A virtual LAN, known as a VLAN, is a logically-independent network. Several VLANs can co-  
exist on a single physical switch. It is usually refer to the IEEE 802.1Q tagging protocol.  
Voice over IP  
VoIP encompasses many protocols. All the protocols do some form of signaling of call  
capabilities and transport of voice data from one point to another. e.g.: SIP, H.323, etc.
