Failover Config Challenge

3 Site WAN, Distributed CMs w/ PRI gateways, Centralized Unity Server:

Site A is a CM Cluster

Site B is a CM Cluster w/ Unity

Site C is a CM Cluster

Inbound calls to sites A and C route via ICTs to site B then to Unity Call Handlers. In the event either WAN link is down I want to route the call to an attendant DN. I know this is possible with VoIP dial peers using preference commands and translation patterns (but I had H323 issues with this), however I have the calls routing from the PSTN directly to the CM then across the ICT. Can this be accomplished in the CM?

For example:

PSTN>SITE A ROUTER>VOIP TO SITE A CM>ROUTE PATTERN MATCH TO ICT>SITE B CM>REDIRECT TO UNITY (this works flawless)

on Failover:

PSTN>SITE A ROUTER>VOIP TO SITE A CM>(WAN DOWN)>TRANSLATE TO LOCAL ATTENDANT DN>RING IP PHONE

Any ideas?

Re: Failover Config Challenge

Often times complex configuration & troubleshooting issues are best addressed in an interactive session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

To utilize the resources at our Technical Assistance Center, please visit http://www.cisco.com/tac and to open a case with one of our TAC engineers, visit http://www.cisco.com/tac/caseopen

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.
