MAKING CALLS USING IP ADDRESSES

Direct IP Call allows two phones to talk to each other in an ad-hoc fashion without a SIP 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 connected through a router using public or private IP addresses (with necessary

port forwarding or DMZ).

To make a direct IP call, please follow the steps below:

 When phone is at idle state, press any number key or * key to bring up “Onhook Dialing” page;

 Press round menu key or "DirectIP" soft key;

 Input the target IP address (Please see example below) ;

 Press "OK" soft key to dial.

For example:

If the target IP address is 192.168.1.60 and the port is 5062 (i.e., 192.168.1.60:5062), input the following:

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 GXP2140/GXP2160 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 address. This is possible only if both

phones are under the same LAN/VPN. This simulates a PBX function using the CSMA/CD without a SIP

server. Controlled static IP usage is recommended.

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";
