Managing Calls
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 Aastra
Web UI. However, you must use the Aastra Web UI to set the per-line call for-
ward settings. The per-line settings override the settings for global call for-
warding.
