DIRECT IP CALL
Direct IP Call allows GVC3200 and another VoIP device to talk to each other in an ad-hoc fashion without
a SIP proxy. VoIP calls can be made between these two if:
• Both GVC3200 and VoIP phone have public IP addresses
Or
• Both GVC3200 and VoIP phone are on the same LAN / VPN using private or public IP addresses
Or
• NAT is disabled or GVC3200 NAT is disabled.
Both devices 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. Access the dial screen on GVC3200.
2. Press the red shortcut key on the remote control to bring up call mode setting screen, set the mode
to "IP Call".
3. Input the target IP address. For example, if the target IP address is 192.168.124.123 and the port is
5062, input the following:
192*168*124*123#5062
The * key represents the dot (.) and the # key represents the colon (:).
4. Press the yellow shortcut key on the remote control to select "Audio Call" or "Video Call".
5. Press on the remote control to dial out.
