2. Introduction  
This Phone is an advanced phone that allows users to achieve perfect voice communication over  
the IP network without using a personal computer. Not only does the Phone support all the  
conveniences and functions of a digital key system phone, it also perfectly integrates all the merits  
and features of analog and IP phones over the data communication system. As voice signals are  
automatically compressed using audio CODECs, they can be transmitted over a low bandwidth  
without interference from other data signals. Furthermore, to provide consistent superior voice  
quality over varying and congested IP network conditions, the Phone is equipped with advanced  
Quality of Service (QoS) technologies such as CODEC negotiation, enhanced jittering technology,  
lost packet reconstruction, echo cancellation, and packet delay recovery.  
For Technical Support please call 1-800-648-4921.

6. Quick Installation  
WARNING  
ƒ The minimum requirements for using UIP312 are network configuration such as DHCP, IP  
Address, Net Mask, Gateway, DNS, etc., and GK address and alias configuration.  
ƒ If above requirements are not satisfied, consult your network administrator.  
6.1 Installing the Phone  
ƒ Unpack all the contents you received with your Phone.  
ƒ Connect your activated Local Area Network (LAN) cable to the UPLINK port on the back of the  
Phone as shown in Figure 1  
ƒ Connect the power adapter to an AC outlet and connect the jack to the DC-IN-18V on the back  
of the Phone (See Note).  
ƒ If you use this phone with a PC, connect one end of the UTP cable (2m) to the Downlink port  
and the other end to your PC’s LAN card. (The Phone has an internal SWITCH HUB in itself.)  
(DC-IN-18V)

6.3 Placement of the Phone  
ƒ The phone includes a footstand. When using the phone on a desk, the footstand can be used  
to provide optimum view of the display, as shown in Figure 2.  
ƒ Alternatively, you can mount the phone on the wall using the footstand as a mounting bracket  
as shown in Figure 3. In this position, the small tab that is located at the base of ear-piece rest  
must be removed, rotated 180 degrees, and reinserted. The tab as shown in Figure 4 will keep  
the handset from falling from the phone when the phone is vertically placed.  
Tab  
Footstand

6.4 Using Power over LAN (POL)  
ƒ You may use Power Over LAN feature with a power adapter at the same time.  
1. If you plug in the adapter first to the phone, and then plug in the POL capable UTP-cable, the  
phone will continue to receive power from the adapter. At this point, if you disconnect the adapter  
from the phone, the phone will reboot, go through the POL startup procedure and start to use the  
POL as its power source.  
2. If you plug in the POL capable UTP-cable first to the phone, and then plug in the adapter, the  
phone will continue to receive power from the POL cable. At this point, if somehow the POL stops  
supplying power to the phone, for instance, when the user disconnects the LAN cable, the power  
source of the phone will switch over to the adapter in a seamless manner without rebooting.  
Note: UIP312 supports the POL service in the uplink ethernet port only, and does not  
support the POL service in the downlink ethernet port.

TIP : Waiting Call  
This is an example of Waiting Call.  
Let’s say there are Phone A, B, and C.  
Step 1. Phone B makes a call to Phone A. The connection is established between the two.  
Step 2. Phone C makes a call to Phone A. You will see the Caller ID info of Phone C on the  
Phone A’s screen.  
Step 3. Phone A’s user press the FLASH button, and now talk to Phone C. At this point, Phone B  
is put on hold and Phone B’s user will be hearing some music.  
Step 4. Phone A’s user press the FLASH button. At this point, Phone C is placed on hold and its  
user will hear music. Phone A is now talking to Phone B.  
Step 5. Phone A’s user press the FLASH button again. Phone B is placed on hold. Phone A and  
Phone C are now talking to each other.  
Step 6. Phone A disconnects the call with Phone C. At this point, Phone B’s user will no longer  
hear the music, and instead, will hear ring back tone.  
Step 7. Shortly after, Phone A rings. At this point, Phone A might not display the Caller ID info. If  
no Caller ID info is displayed, it won’t be saved in Call history either. Phone A’s user may  
pick up the phone before ringing in this case.  
Step 8. Phone A’s user pick up the phone and is able to resume talking to Phone B.  
If this Waiting Call feature is not working, contact your administrator.

7.4 Disconnecting a call  
NOTE : You cannot disconnect existing calls by pressing the LINE1 or LINE2 key  
• Unlike the speakerphone button, LINE1 key and LINE2 key are only used for off hook or  
switching lines.  
7.4.1 Disconnecting when a single line is in use:  
• If you wish to disconnect a call simply hang up the handset.  
• If you are using the speakerphone, simply press the speakerphone button.  
Note: While you are talking through the speakerphone with the handset off the hook,  
pressing the speakerphone button will let you switch to the handset.  
7.4.2 Disconnecting when a Multiple lines are in use:  
Depending on the situation, there are different ways to disconnect a call when multiple lines are in  
use.  
1) Disconnecting a call using the handset:  
ƒ If you are on Line 1 and you receive a call on Line 2, answer Line 2 by switching lines.  
Line 1 will automatically be placed on hold.  
ƒ If you wish to disconnect Line 2, either press the hook switch or return the handset to  
the handset cradle. If you disconnect Line 2 by pressing the hook switch, you will  
automatically be reconnected to Line 1.  
ƒ If you disconnected Line 2 by returning the handset to the handset cradle, you will be  
reconnected to Line 1when you pick up the handset. Should you forget to pick up the handset,  
this phone will remind you that Line 1 is on hold.  
ƒ If after answering Line 2, Line 2 disconnects the call before you do, disconnect  
Line 2 by using the handset or hook switch. If you do not disconnect Line 2 before reconnecting  
to Line 1, the phone will automatically disconnect Line 2 after several seconds.  
( Note: If you choose to have all lines available immediately, disconnect Line 2 using the  
handset or hook switch before reconnecting to Line 1.)  
ƒ If, when you are on Line 1, Line 2 is on hold and you wish to disconnect Line 2, switch to  
Line 2. Doing so will activate Line 2 and place Line 1 on hold automatically. To disconnect  
Line 2, either press the hook switch or return the handset to the cradle.  
If you disconnect Line 2 by pressing the hook switch, you will automatically be reconnected to  
Line 1. If you disconnect Line 2 by placing the handset in the cradle, you will be reconnected to  
Line 1 when you pick up the handset. Should you forget to pickup the handset, the phone will  
remind you that a call is on hold.

2) Disconnecting a call using the speakerphone button:  
ƒ If you are on the speakerphone on Line 1 and you receive a call on Line 2, answer Line 2 by  
switching lines as described above. To disconnect Line 2, push the speakerphone button.  
Doing so will automatically disconnect Line 2. To reconnect to Line 1, push the speakerphone  
button again or pick up the handset.  
TIP : Reminder Ring  
• Let's say that LINE 1 and LINE 2 are both in use.  
• LINE 1 is on hold and LINE 2 is the active line. The handset is being used.  
• At this point, the user disconnects the LINE 2 call by hanging up. LINE 1 is still on hold and  
LINE1 LED keeps blinking.  
• If the user doesn't pick up the handset, press the speakerphone button or press the LINE 1  
button within 6 seconds, in order to remind the user of the existing call on LINE 1, UIP312 starts  
ringing and flashing the Message Lamp as if there is an incoming call. This is called "Reminder  
Ring".  
(And just for your own reference, the 6 seconds of delay is derived from the interval between  
each ring of the regular incoming calls.)

8.7 Caller ID  
ƒ Caller ID service can be used with the Phone.  
ƒ Caller ID allows you to see information about the caller before you answer the phone.  
ƒ Caller ID will provide you with a caller’s information even if you are already on another call.  
ƒ In some special circumstances, the Caller ID will display “Private”, “Out of Area”, or no  
information at all instead of the caller’s number. For more information consult with your  
administrator.  
Note: The Phone provides Caller ID as default. If Caller ID does not work, contact your  
administrator.  
8.8 Call information  
If you want to see the dialing info of a call you made or the Caller ID info of a received call  
while you are talking on a line, press the CANCEL button.  
For instance, you made a call to “4800000” and are talking on LINE1 and you are having an  
incoming call with the Caller ID of “John” and its number “4800001”. Then if you pressed the  
CANCEL button, you will see a display like below.

When receiving a call while the headset is connected to the phone, pressing the Speaker Phone  
button will let you talk and hear through the headset, and picking up the handset will let you talk  
and hear through the handset.  
2. While you were using the handset  
If you plug the headset in while you were using the handset, you will speak and hear through the  
headset. At this point, if the headset adapter is plugged back out, you will be able to talk and  
hear through the handset again.  
3. While you were using the speaker phone  
If you plug the headset in while you were using the speaker phone, you will speak and hear  
through the headset. If the headset is plugged back out, you will be able to talk and hear through  
the speaker phone again.  
TIP: Using any headset that is not recommended by Uniden might possibly cause the other person  
on the line sounds relatively louder or quieter. If this happens you will have to adjust the volume  
using the Volume key as well as the person on the other end of the line.

Program the Speed dial [F1] key as follows.  
[F1]Name : AAA Bank ( Name is not mandatory. )  
[F1]Number : 4801111PPPPP11231234PPPP0000#

15. Glossary  
DiffServ  
Alias  
Differentiated Services (DiffServ, or DS) is a  
protocol for specifying and controlling network  
traffic by class so that certain types of traffic  
get precedence - for example, voice traffic,  
which requires a relatively uninterrupted flow  
of data, might get precedence over other kinds  
of traffic.  
Alias is the user’s telephone number.  
Centrex  
Business and personal service provided by  
a telephone company or service provider.  
Part of custom-calling services.  
DNS  
The domain name system (DNS) is the way  
that Internet domain name are located and  
translated into Internet protocol addresses. A  
domain name is a meaningful and easy-to-  
remember "handle" for an Internet address.  
CODEC  
In this context, the term is an acronym for  
"coder/decoder." This type of codec  
combines analog-to-digital conversion and  
digital-to-analog conversion functions in a  
single chip.  
The term codec is also an acronym that  
stands for "compression/decompression.  
Gateway  
A gateway is a network point that acts as an  
entrance to another network. In IP Telephony,  
gateway connects PSTN and IP Network.  
Custom-calling Services  
Extra services ordered through a telephone  
company or service provider.  
May include Centrex services.  
H.323  
H.323 is a standard approved by the  
International Telecommunication Union (ITU)  
in 1996 to promote compatibility in videoconference  
transmissions over IP networks.H.323 was  
originally promoted as a way to provide consistency  
in audio, video and data packet transmissions in  
the event that a local area network (LAN) did not  
provide guaranteed service quality (QOS).  
DHCP  
DHCP (Dynamic Host Configuration Protocol)  
is a protocol that lets network administrators  
manage centrally and automate the assignment  
of Internet Protocol (IP) addresses in an  
organization's network. Using the Internet's  
set of protocol(TCP/IP), each machine that can  
connect to the Internet needs a unique IP address.  
Page 67  
Download from Www.Somanuals.com. All Manuals Search And Download.  
IP Telephony  
PSTN  
IP telephony (Internet Protocol telephony) is 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.  
The PSTN (public switched telephone network)  
refers to the world's collection of interconnected  
voice-oriented public telephone networks, both  
commercial and government-owned. It's also  
referred to as the Plain Old Telephone Service.  
UTP  
Unshielded twisted pair is the most common  
kind of copper telephone wiring.  
Twisted pair is the ordinary copper wire that  
connects home and many business  
computers to the telephone company.  
Jitter  
Jitter is the deviation in or displacement of  
some aspect of the pulses in a high-frequency  
digital signal. As the name suggests, jitter can be  
thought of as shaky pulses. The deviation can be  
in terms of amplitude, phase timing, or the width  
of the signal pulse.  
VoIP  
VoIP (voice over IP - that is, voice delivered  
using the Internet Protocol) is a term used in IP  
Telephony for a set of facilities for managing  
the delivery of voice information using the  
Internet Protocol(IP). In general, this means  
sending voice information in digital form in  
discrete Packet rather than in the traditional  
circuit-committed protocols of the public  
switched telephone network.  
LAN  
A local area network (LAN) is a group of computers  
and associated devices that share a common  
communications line and typically share the  
resources of a single processor or server within a  
small geographic area (for example, within an office  
building).  
MAC address  
On a local area network (LAN) or other network,  
the MAC (Media Access Control) address is  
your computer's unique hardware number. (On  
an Ethernet LAN, it's the same as your Ethernet  
address.) When you're connected to the Internet  
from your computer (or host as the Internet protocol  
thinks of it), a correspondence table relates your IP  
address to your computer's physical (MAC) address  
on the LAN.
