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:

Press MENU button to bring up main menu;

Select "Direct IP Call" using the navigation arrow keys;

Press MENU to enter the Direct IP Call mode;


Press "OK" softkey to dial.
