We have a CCM 3.1.2c (migrating to 3.1.3 on one week) with separate servers for IPCC setup (ICM, IPIVR, etc.)
We have gone through a farily lengthy process of trying to figure out how to configure our Calling Search Spaces, and how IPCC handles call routing and connections.
We have all of our on-cluster calls working perfectly. PSTN calls reach the correct queues, internal callers can reach them as well.
The problem now is that we have the infamous "Cluster B" (there is also a C and a D btw)connected via InterCluster trunks, and I can not seem to get a call to complete properly to the IPCC across the ICT. Looks like this: ClusterB -> Gatekeeper -> ClusterA
I know my Gatekeeper config is AOK because the CTI Route Points are in the same range as the extensions and those calls complete properly. I also redirected the CTI Route Point in question to a line appearance and that worked.
I tried changing codec to g.711, and back to g.729 with no effect. The only way I can make this work is that once the call is received on ClusterA, to force it through a "hard gateway", 6608 with a PRI looped into another PRI port.
When I do that, the calls complete properly and I go into queue.
Anybody have this working? or, anybody know of another workaround?
