Callamnager Upgrade

[stuart.pannell]

I have just upgraded one of our CCM clusters from 3.3 to 4, we now have a problem with phones still on the 3.3 cluster dropping when calling into unity after 100secs the unity 4(3) box is integrated into the CCM4 box, do you have an ideas of what could be causing the timeout!

Cheers

CCM 4.x->Unity is SIGNIFICANTLY different from CCM 3.x->Unity integration.

In CCM 3.x, you are forwarding from one port to the next. In CCM 4.x, the idea of hunt groups is introduced for voice mail ports; you can't forward the vm ports anymore. As there are many changes in the database links between the mismatched CCM version in the ccm-cluster, I think it's best to revisit this question after you have finished upgrading CCM to 4.x and have reconfigured the vm ports per the doc below.
