I have a 2-site call manager 4.2.3 cluster. Pub at one site and sub at other with a metroE link between them.
Each site has their own gateways and telco pri's.
I'm looking for a way to have callmgr automatically reroute a 4-digit site-to-site call over the pstn in the event the metroE link goes down.
My understanding is that the AAR feature would not work in this scenerio, in essance, call mgr would not "know" the link is down.
If anyone knows of a way to make this work I'd appreceiate hearing it.
