Trunk Communications between CallManager Clusters

Hello,

Does anyone know of a way to connect 2 CallManager clusters together so that phones from 1 cluster can call phones on the other cluster and do it without creating route patterns? I wold love it if the server cold somehow be aware of the other servers database and just route the calls accordingly

All replies rated!

Thanks!

Re: Trunk Communications between CallManager Clusters

sorry, only an ICT with appropriate routePattern can tell call manager where to send a call.

perhaps you can summarize the patterns in the other cluster. ie: 2XXX

i have the same scenario here except all the DNs on the other cluster are not contiguous and share the same range. i have a couple hundred extra routePatterns just for ICT calls....arg

Re: Trunk Communications between CallManager Clusters

Thanks. I didn't think it was possible but thought I would throw it out there and see what happened. I have the same deal. non-contiguous number ranges. What a pain. I will have a few hundred route patterns as well. Thanks for your help!

Hey Cisco, since Call Manager is THE platform for IP telephony in businesses how about getting us a resolution to this issue? As CM gets a wider install base it is only going to happen more and more.

Re: Trunk Communications between CallManager Clusters

Have you tried to configure InterCluster Trunk?

Device>Trunk, and maybe using GK or not, yo may be able to add the ip addresses of the remote cluster, and vice versa.

But anyway every route must be entered using the intercluster trunk as a GW.
