Call forward allows redirecting an incoming call to a third party. The IP phones support
to redirect an incoming INVITE message by responding with a 302 Moved Temporarily
message. This response contains a Contact header with a new URI that should be tried.
The IP phones offer three types of forward:
 Always Forward -- Forward the incoming calls immediately.
 Busy Forward -- Forward the incoming call when the callee is busy.
 No Answer Forward -- Forward the incoming call after a period of ring time.
The call forward on code or call forward off code configured on the IP phone is used to
inform the server of activating or deactivating the call forward feature. The call forward
on code and call forward off code may vary on different servers.
