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 enable call forwarding on a global
basis or on an individual line-basis, for each line. 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 enable call forwarding on all phones (global settings) or on specific lines
(local settings) of a single phone. For local settings, you can set call forwarding on up
to 9 individual lines.
For global and local 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.

Note:
You can set the global call forward settings using the IP phone UI or the

line call forward settings. The per-line settings override the settings for
global call forwarding.
