Register to a Server

The phone should be configured before it can perform some basic functions. Although the 

phone can make a peer to peer VOIP call (the user must remember the IP address of the 

called party), it is desirable to have a centralized server to provide the directory service. 

This server can be a soft-switch, an IP-PBX, or a simple proxy.

The server has two basic functions:

1) The first is to track active phones and their IP address.
2) The second is passing signaling messages between communication parties.

To make your phone reachable in this VOIP network, your phone has to register to the 

server so that when someone dials your phone number the server knows where you are 

and informs your IP phone that someone is calling.
