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 "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.
