Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other network by using an alternate number when Cisco CallManager 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. The AAR group represents the dialing area where the line/directory number (DN), the Cisco voice mail port, and the gateway are located.
On a centralized design, AAR uses the calling number external phone mask to prepend the additional digits to allow a 10 digit dialing out to the pstn but with distributed design of ICT, AAR DOES NOT KNOW the calling number "external mask" as that is defined on the other CM cluster.
