12.14.1 Calling Methods
The Prestige can dial a telephone number by using the SIP proxy server or an IP address.

• Select P2P to an IP address to place a call without first going through the SIP proxy
server. This is called an IP to IP (or peer to peer) call. You need to enter the IP address of
the callee or another SIP proxy server.
