MAKING PHONE CALLS
2 CALLS WITH 1 SIP ACCOUNT
GXP1100/GXP1105 can support up to two lines “virtually” mapped to one SIP account. By picking up the
handset, the GXP1100/GXP1105 will be in off hook state and the dial tone will be heard. To make a call,
dial out the number with the current line.
During the call, users can press the FLASH key to hold the current call and make/answer another call. If
they are 2 calls established, users can switch the two lines by pressing the FLASH key.
COMPLETING CALLS
The GXP1100/GXP1105 allows you to make phone calls after picking up the handset. There are four ways
to complete calls.
Dial. Enter the number and send out.
Take handset off hook. You shall hear dial tone from the handset;
Enter the number;
Press SEND key or # to dial out.
Redial. Redial the last dialed number.
Take handset off hook. You shall hear dial tone from the handset;
Press SEND key.
Speed Dial. Dial the number configured as Speed Dial on Multi Purpose Key.
Go to GXP1100/GXP1105 Web GUI->Settings->Programmable Keys, configure the
Multi-Purpose Key's Key Mode as Speed Dial. Enter the Description and Value (the number to be
dialed out) for the Multi-Purpose Key. Click on "Save and Apply" at the bottom of the Web GUI
page;
Take handset off hook. You shall hear dial tone from the handset;
Press the configured Speed Dial key.
Call Return. Dial the last answered call.
Go to GXP1100/GXP1105 Web GUI->Settings->Programmable Keys, configure the Multi
Purpose Key's Key Mode as Call Return. No Value has to be set on the Multi Purpose Key for Call
Return;
Take handset off hook. You shall hear dial tone from the handset;
Press the configured Call Return key to dial out.

FIRMWARE VERSION 1.0.8.4 GXP1100/GXP1105 USER MANUAL Page 17 of 53
Note:
After entering the number, the phone waits for the No Key Entry Timeout (Default timeout is 4 seconds,
configurable via Web GUI) before dialing out. Press SEND or # key to override the No Key Entry
Timeout;
If digits have been entered after handset is off hook, the SEND key will works as SEND instead of
REDIAL;
By default, # can be used as SEND to dial the number out. Users could disable it by setting "User # as
Dial Key" to "No" from Web GUI->Account->Call Settings.
MAKING CALLS USING IP ADDRESSES
Direct IP Call 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 the same LAN/VPN using private or public IP addresses; or
Both phones can be connected through a router using public or private IP addresses (with necessary
port forwarding or DMZ).
To make a direct IP call, please follow the steps below:
Take handset off hook. You shall hear dial tone from the handset;
Press *** to enter the GXP1100/GXP1105 IVR menu;
Enter 47 for Direct IP Call. After hearing "Direct IP Calling", the dial tone will be heard again;
Enter the target IP address to dial (Please see example below).
For example:
If the target IP address is 192.168.1.60 and the port is 5062 (i.e., 192.168.1.60:5062), input the following:
192*168*1*60#5062. The * key represents the dot (.), the # key represents colon (:). Wait for about 4
seconds and the phone will initiate the call.
Quick IP Call Mode:
The GXP1100/GXP1105 also supports Quick IP Call mode. This enables the phone to make direct IP calls
using only the last few digits (last octet) of the target phone's IP address. This is possible only if both

FIRMWARE VERSION 1.0.8.4 GXP1100/GXP1105 USER MANUAL Page 18 of 53
phones are under the same LAN/VPN. This simulates a PBX function using the CSMA/CD without a SIP
server. Controlled static IP usage is recommended.
To enable Quick IP Call Mode, go to GXP1100/GXP1105 Web GUI->Settings->Call Features, set "Use
Quick IP Call Mode" to "Yes". Then take the handset off hook and dial #xxx where x is 0-9 and xxx<255.
Press # or SEND and a direct IP call to aaa.bbb.ccc.XXX will be completed. "aaa.bbb.ccc" is from the local
IP address regardless of subnet mask. The number #xx or #x are also valid. The leading 0 is not required
(but it's OK).
For example:
192.168.0.2 calling 192.168.0.3 -- dial #3 followed by # or "SEND";
192.168.0.2 calling 192.168.0.23 -- dial #23 followed by # "SEND";
192.168.0.2 calling 192.168.0.123 -- dial #123 followed by # "SEND";
192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3.
Note:
The # will represent colon ":" in direct IP call rather than SEND key as in normal phone call;
If you have a SIP server configured, direct IP call still works. If you are using STUN, direct IP call will
also use STUN;
Configure the "User Random Port" to "No" when completing direct IP calls.
ANSWERING PHONE CALLS
RECEIVING CALLS
Single incoming call. Phone rings with selected ring tone. Answer call by taking handset off hook;
Multiple incoming calls. When another call comes in while having an active call, the phone will
produce a Call Waiting tone (stutter tone). Answer the incoming call by pressing the FLASH key. The
current active call will be put on hold.
DURING A PHONE CALL
CALL WAITING/CALL HOLD
Hold. Place a call on hold by pressing the HOLD key;
Resume. Press the HOLD key again to resume;
