AAR on SRST router

ev1205

Level 2

Hello everyone.

We have a customer with a CUCM version 10.5.2.

They have one Headquarters and one remote site, on the remote site we have configured with SRST and it has been working very good.

Now customer want to implement AAR in order to reroute automatically  internal calls to PSTN during WAN outage.

The AAR configuration has been implemented properly on CUCM, but we would like to validate proper configuration for AAR on voice gateway during SRST stage (on WAN outage).

Best regards

I don't think you understand how AAR works, AAR is not meant to solve call routing if there is a WAN outage.

AAR is meant to re-route calls over the PSTN if there is not enough BW to make the call over the WAN. And that would be based on locations and regions.
