---> Do I need a service provider? Can I make IP-to-IP call between video phones?

Yes, you need to have an Internet Telephony Service Provider (ITSP). You can also use “Direct IP Call” to talk to each other in an ad hoc fashion without a SIP proxy.  “Direct IP Call” can be made between two phones if:

• both phones have public IP addresses, or
• both phones are in a 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, press OK button to bring up MAIN MENU.  Select “Direct IP Call”.  Press OK key to bring up the input interface and then key in the 12-digit target IP address. Press OK key to initiate call.
