AAR Settings
AAR (Voice Mail, AAR
Destination Mask, AAR
Group)
The settings in this row of fields specify treatment of calls for which insufficient bandwidth
exists to reach the destination. Automated alternate routing (AAR) handles these calls that are
routed to the AAR Destination Mask or Voice Mail.
Configure the following values:
• Voice Mail—Check this check box to use settings in the Voice Mail Profile Configuration
window.
When this check box is checked, Cisco Unified Communications Manager ignores the
settings in the Coverage/Destination box and Calling Search Space.
• AAR Destination Mask—Use this setting instead of the external phone number mask to
determine the AAR Destination to be dialed.
• AAR Group—This setting provides the prefix digits that are used to route calls that are
otherwise blocked due to insufficient bandwidth. An AAR group setting of None indicates
that no rerouting of blocked calls will be attempted.
Retain this destination in the
call forwarding history
This setting determines whether the AAR leg of the call will be present in the call forwarding
history. If you uncheck the check box, the AAR leg of the call is not present in the call history.
If you check the check box, the AAR leg of the call will be present in the call history.
By default, the directory number configuration retains the AAR leg of the call in the call
history, which ensures that the AAR forward to voice-messaging system will prompt the user
to leave a voice message.
