Use the phonebook feature to store and later retrieve names and corresponding telephone 
numbers. 

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

• Select Proxy to have the SIP server make the connection.
• 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.

Click PHONE BOOK to open the following screen.

Leave this field set to the default if your VoIP service provider did not give you a 

server port number for STUN.
