1.
Press MENU button to bring up main menu.
2.
Select "Direct IP Call" using the navigation arrow keys.
3.
Press MENU to enter the Direct IP Call mode.
4.
Input the 12-digit target IP address (Please see example below).
5.
Press the "More" softkey to make sure the softkey selection "IPv4" or "IPv6" is correctly selected
depending on your network environment.
6.
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 GXP1610/GXP1615/GXP1620/GXP1625/GXP1628/GXP1630 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". Clicking on "Save and Apply" on the bottom of 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 is 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.
Notes:

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 "Use Random Port" to "No" when completing direct IP calls. The option “Use Random
Port” is under phone’s Web GUI Settings  General Settings page.
