CCM publisher subscriber issue

mohammedanasshaikh · ‎08-11-2008

Hi all,

I have a CCM 6.1 and a ccm 4.2 both are connected to a normal switch. there are two ip phones registered with each of the call managers and calls can be made between any two phones registered with the same call manager. i wanted to set up a scenario where these two call managers would together form a cluster with one as the subscriber and the other as publisher and if i m not wrong this will aloow me to make callls between all 4 ip phones that i have... please help me know how i could achieve this

You cannot have a cluster with servers of different versions. You can, however, make calls between the clusters. See the following post.

Are they both publishers now? If so try setting up an intercluster trunk between the two servers.
