Is AAR supported in a distibuted call processing model? I have two sites running its own call manager clusters. Call between the 2 sites are done using Inter-custer trunk (ICT) w/o gatekeeper over the IP WAN. I am using Location to do Call Admission Control. In the event of bandwidth not enough through the ICT, can I use AAR to reroute to PSTN?
In the event of IP WAN failure, can i force it to reroute to PSTN as well?
Well, it might not be that straight-forward. It also depends on your dial plan. Let's say he's wants to use AAR to re-route and do some digit manipulation.
However, creating a route group and route list with multiple routes is the easiest way if you don't need to do any digit manipulations.
