Call Forward
You can forward calls from any line on your phone to a contact. There are two ways of forwarding your calls:
l
Forward calls in special situations, such as when the phone is busy or there is no answer, or forwarding all
incoming calls to a contact immediately.
You can set the phone not to forward a call coming from authorized numbers.
l
Manually forward an incoming call to a number.
