I am running CCM 4.1(3) and am trying to find a way to route to an IP phone when the PSTN gateway is down. I created an intercluster trunk in CCM that points to itself (same cluster). I used this as the second choice route for my PSTN patterns. I have this running in my lab and it works very well. As long as I only give the inbound side of the ICT access to a specific partition (so I don't get any loops), does anyone see any problems with this? Is this a supported configuration by Cisco? Anyone have any ideas how to do this better or more efficiently?
