5. Press OK key to initiate call
To make a quick IP call, please see next section.
For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g . 192.168.1.60:50 62), input
the following: 192*168*1*60#5062 - The “ * ” key represent the dot“.” ; T he “#” key represent colon “:”. Press
OK to dial out.
Quick IP Call Mode
The GXP21xx also supports Quick IP call mode. This enables t he phone to mak e direct IP-ca lls, usin g only
the last few digits (last octet) of the target phone’s IP-number. This is poss ible only if both phones are in
under the same LAN/VPN. This simulates a PBX function using the C MSA/CD without a SIP server.
Controlled static IP usage is recommended.
Setting up the phone to make Quick IP calls
To enable Quick IP calls, the phone has to be setup first. This is done through the web-s etup func tion. In the
“Advanced Settings” page, set the "Use Quick IP-call mode to YES. When #xxx is dialed, where x is 0-9 and
xxx <=255, a direct IP call to aaa.bbb.ccc.XXX is completed. “aaa.bbb.ccc” is f rom the local IP address
regardless of subnet mask. The numbers #xx or #x are also valid. The l eading 0 is not required (but OK).
For example:
192.168.0.2 calling 192.168.0.3 -- dial #3 follow by SEND or #
192.168.0.2 calling 192.168.0.23 -- dial #23 follow by SEND or #
192.168.0.2 calling 192.168.0.123 -- dial #123 follow by SEND or #
192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0. 3
NOTE: If you have a SIP Server configured, a Direct IP-I P still works. If you are using STUN, the Direct IP-
IP call will also use STUN. Configure the “Use Rando m Port” to “NO” when completing Direct IP calls.
