Call forward allows users to redirect an incoming call to a third party. IP phones redirect
an incoming INVITE message by responding with a 302 Moved Temporarily message,
which contains a Contact header with a new URI that should be tried. Three types of call
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.
Call forward can be configured on a phone or per-line depending on the call forward
mode. The following describes the call forward modes:
Phone (default): Call forward feature is effective for all accounts on the IP phone.
Custom: Call forward feature can be configured for each or all accounts.
