Explanation:
Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other
network by using an alternate number when Cisco Unified Communications Manager blocks a call
due to insufficient location bandwidth. With automated alternate routing, the caller does not need
to hang up and redial the called party.
