
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 GXP1160/GXP1165 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
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 phone's Web GUI->Settings->Call Features, set "Use Quick IP Call
Mode" to "Yes". Click on "Save and Apply" 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 key;

192.168.0.2 calling 192.168.0.23 -- dial #23 followed by # SEND key;

192.168.0.2 calling 192.168.0.123 -- dial #123 followed by # SEND key;

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.
