Calliung CCM 4.2 and CME locations

I trying to determine the best method to route calls between a CCM 4.2 and CUE location. I have a Intercluster Trunk to route calls to the CME site via an MPLS network. In the event of a failure I want to end the calls over the PSTN. What would be the easiest method, AAR, multiple, Route Patterns, other? Your input is appreciated.

You need to configure a route list which contains the H323 GW and then the PSTN GW, adding the necessary prefixes for PSTN

This I have done. How do set priority between Route-list containing the ICT and the PSTN.

Let's get something straight, an ICT is to connect 2 CUCM clusters. To connect a CUCM to a CME you need to configure the CME as an H323 GW. So there can't be an ICT in this config.

H323 1st element

PSTN 2nd element

Re: Calliung CCM 4.2 and CME locations

You are correct I have a H.323 gateway configured to access my CME. I guess my problem is in building the Route Group, my H.323 GW is not listed as a possible element which I can choose. I only see my PSTN GWs

If the H323 is already in another RG or selected under a route pattern, it cannot be used again. You need to take it out from any other RG or RP to use it.
