MAKING PHONE CALLS
HANDSET, SPEAKER AND HEADSET MODE
The GXP1400/GXP1405 allows users to switch among handset, speaker or headset when making calls.
Press the Hook Switch to switch to handset; press the Headset button to switch to headset; or
press the Speaker button to switch to speaker.
2 SIP ACCOUNTS AND LINES
GXP1400/GXP1405 can support up to 2 independent SIP accounts. Each account is capable of
independent SIP server, user and NAT settings. Each of the line buttons is "virtually" mapped to an
individual SIP account. In off hook state, select an idle line and the dial tone will be heard.
To make a call, select the line you wish to use. The corresponding LINE LED will light up in green. The
user can switch lines before dialing any number by pressing the LINE buttons.

FIRMWARE VERSION 1.0.4.23 GXP1400/GXP1405 USER MANUAL Page 15 of 60
For example: If 2 independent accounts are registered on GXP1400/GXP1405, when LINE 1 is pressed,
the LINE 1 LED will light up in green. If LINE 2 is pressed, the LINE 2 LED will light up in green and the
subsequent call will be made through SIP account 2.
Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the
“virtually” mapped line is in use, the GXP1400/GXP1405 will flash the other available LINE in red. A line is
ACTIVE when it is in use and the corresponding LED is red.

code set up already, users might not necessarily need toggle to paging mode in the call screen on
GXP1400/GXP1405. Simply dial the feature code with extension as a normal call.
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:
•Press MENU button to bring up main menu;
•Select "Direct IP Call" using the navigation arrow keys;
•Press MENU to enter the Direct IP Call mode;
•Input the 12-digit target IP address (Please see example below);
•Press the "More" softkey to make sure the softkey selection "IPv4" or "IPv6" is correctly selected
depending on your network environment;
•Press "OK" softkey to dial.
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 GXP1400/GXP1405 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 1.0.4.23 GXP1400/GXP1405 USER MANUAL Page 18 of 60
phones are under the same LAN/VPN. This simulates a PBX function using the CMSA/CD without a SIP
server. Controlled static IP usage is recommended.
To enable Quick IP Call Mode, go to GXP1400/GXP1405 Web GUI->Advanced Setting page, set "Use
Quick IP Call Mode" to "Yes". Click on "Update" on the bottom of the Web GUI page to take the change. To
make Quick IP Call, take the phone off hook first. Then 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. The corresponding LINE key will flash in
red. Answer call by taking handset off hook, or using Speaker/Headset, or pressing the flashing LINE
key;
•Multiple incoming calls. When another call comes in while having an active call, the phone will
produce a Call Waiting tone (stutter tone). The other LINE key will flash in red. Answer the incoming
call by pressing the flashing LINE key. The current active call will be put on hold automatically.
DO NOT DISTURB
Do Not Disturb can be enabled/disabled by pressing the MUTE/DND button on the phone when the phone
is in idle. Or users could set it from phone's Menu following the steps below:

FIRMWARE VERSION 1.0.4.23 GXP1400/GXP1405 USER MANUAL Page 19 of 60
