[cisco-voip] Multiple CM Clusters - 1 Unity system

[Matt Slaga (US)]

Should not be an issue, just check the compatibility matrix for the version of the TSP you are currently running.

Does the unity server care what versions of call manager it talks to?

The main cluster with 99% of the users is 7.x.

The second cluster is only staying in service to server our Call Centers until they are migrated to Avaya.  I only have a few users staying on that system that have voicemail.  That CM cluster is 4.2(3).

A few ports for the smaller system should be plenty.

It is absolutely possible, however you have to carve out the Unity ports between the systems, as they cannot be shared.  I.e, if you have 32 ports and 4 systems, you could do 8 ports per system.  You also have to configure each UCM cluster in the Unity TSP .

Is it possible for multiple CM Clusters (different Versions) to point to one common Unity Server.
