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.

l Allow or disallow users to forward an incoming call to an international telephone number (the prefix is 00).
l Enable or disable forward emergency feature and specify forward authorized numbers. These numbers will not
be forwarded when the call forward feature is enabled. The incoming call will not be logged in the Forwarded
