Quick IP Call Mode
The GXP2124 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-number. This is possible only if both phones are in
under the same LAN/VPN. This simulates a PBX function using the CMSA/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-setup function. In the
web GUI->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 from the local IP
address
regardless
of subnet mask. The numbers #xx or #x are also valid. The leading 0 is not required (but
OK).
For example:
192.168.0.2 calling 192.168.0.3 -- offhook the phone, dial #3 followed by DIAL softkey or SEND
192.168.0.2 calling 192.168.0.23 -- offhook the phone, dial #23 followed by DIAL softkey or SEND
192.168.0.2 calling 192.168.0.123 -- offhook the phone, dial #123 followed by DIAL softkey or SEND
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-IP still works. If you are using STUN, the Direct IP-IP
call will also use STUN. Configure the “Use Random Port” to “NO” when completing Direct IP calls.
