Virtual Multi-Purpose Keys - Grandstream Networks GXP21 Series User Manual

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'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.
