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;

 Both phones are on the same LAN/VPN using private or public IP addresses;

 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.
