[cisco-voip] AAR for WAN outage

[Malcolm Caldwell]

Hello,

Can AAR be used to re-route calls when a WAN IP link is down, or is it
only used when there is insufficient location bandwidth?

For example our branch offices have 2821 routers with 2xBRI interfaces.
The routers run SRST.  From our central site we normally dial 4-digits
to reach a phone at the branch office.

During a WAN outage, the phones work due to SRST, but to call the site
from our central site we must dial the full national numbers.

Can AAR help here?
