Call Forward
You can forward calls from any line on your phone to a contact. There are two ways of forwarding your
calls:
 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.
 Manually forward an incoming call to a number.

You can change the following call forward settings:
 Enable or disable the call forward feature. If disabled, the users have no permission to configure call
forward on their phone.
 Choose a call forward mode. You can configure call forward for all lines or specific lines.
 Allow or disallow users to forward an incoming call to an international telephone number (the prefix
is 00).
 Enable or disable forward emergency feature and specify forward authorized numbers. These
numbers will not to be forwarded when the call forward feature is enabled. The incoming call will
