[cisco-voip] AAR for WAN outage

[Karl Whitson]

Malcolm,

If you are using CM 4.2 or above you could use the Forward Unregistered setting on the line.  You would enter the full PSTN number on the Unregistered setting (make sure you include the proper CSS).  When the remote site goes into SRST mode (WAN down) the phone will unregister from Call Manager.  When you dial (from the HQ end) the 4 digit extension and the phone is not registered, it will send to the Unregistered setting.

Hope this helps.

Subject: [cisco-voip] AAR for WAN outage

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?
