DIRECT IP CALL
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:
1. Off hook the phone or select account in the idle screen to bring up dial screen on GXV3275;
2. Under "Mode" button in the call screen, tap on it and select the mode as "IP Call";
3. Input the target IP address. 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 (.) and the # key represents the colon (:).
4. Tap on (audio call only) or (video call) to dial out.
