Making Calls Using Ip Addresses - Grandstream Networks GXP2130 User Manual

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 GXP2130/GXP2140/GXP2160/GXP2170/GXP2135 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";
