MAKING CALLS USING IP ADDRESSES

Direct IP Call allows two phones to talk to e ach ot her in an ad-h oc f ashion withou t a SI P proxy. VoIP calls can be made between two phones if:
• Both phones have public IP addresses; or
• Both phones are on the same LAN/VPN using private or public IP addresses; or
• Both phones can be conn ected throu gh a router us ing pub lic or privat e IP addresses (with necess ary
port forwarding or DMZ).
To make a direct IP call, please follow the steps below:
• Press MENU button to bring up main menu;
• Select "Direct IP Call" using the navigation arrow keys;
• Press MENU to enter the Direct IP Call mode;
• Input the 12-digit target IP address (Please see example below);
• Press the "More" softkey to make sure the softkey selection "IPv4" or "IPv6" is correctly selected
depending on your network environment;
• Press "OK" softkey to dial.
For example:
If the target IP address is 1 92.168.1 .60 and the p ort is 50 62 ( i.e., 192.16 8.1.60: 5062) , in put th e fol lowin g: 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 GXP2124 also supports Quick IP Call mode. This enables the phone to make direct IP calls using only the last few digits (last oc tet) 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 CMSA/CD without a SIP server. Controlled static IP usage is recommended.
To enable Qu ick IP Call Mode, go to phone's W eb GUI->Advanced Setting pag e, set "Use Quick IP Call Mode" to "Yes". Click on "U pdat e" on t h e bo ttom of the Web GUI page to take the change . To make Quick IP Call, take the phone off hook f irst. T hen dial #xxx where x is 0-9 and xxx<255. Pr ess # or S END an d a
