Operational IP Phone Features
Call Forwarding
The call forwarding feature on the IP phone allows incoming calls to be forwarded
to another destination. The phone sends the SIP message to the SIP proxy, which
then forwards the call to the assigned destination.
Call forwarding is disabled by default. You can configure call forwarding on a
phone-wide basis or on multi-line phones on a per-line basis. If you have
configured call forwarding on an individual line, then the settings for this line are
used; otherwise, the phone-wide call forward settings are used.
You can configure call forwarding on all phones (global settings) or on specific
lines (local settings) of a single phone.
For call forwarding you can set the following:
• Call forward mode
• Destination number
• Number of rings before forwarding the call (from 1 to 9 rings)
The following are the call forward modes you can set:
Call Forward Mode Description
Off Disables call forward
All Phone forwards all incoming calls
immediately to the specified destination.
Busy Phone forwards incoming calls if the line is
already in use.
No Answer Phone forwards the call if it is not
answered in the specified number of rings
Busy No Answer Phone forwards the call if either the line is
already in use or the call is not answered
in the specified number of rings.
Global
(per-line only)
Phone uses the phone-wide call forward
setting. This is only valid when setting the
mode of individual lines.
