hello, everyone, I have a customer who has an old cluster CUCM 4.2 and in the process of building a new cluster 7. I understand that it is possible to integrate the second cluster to same Unity 4.2? if so, is there any tricky things I need to pay more attend ? thanks

There are two ways to do this.
1. Create a new integration for CUCM 7.1 in Unity.
2. Use a Q.SIG inter-cluster trunkto Tunnel MWI between clusters.
There is an excellent blog post discusiing this topic by William Bell at the link below:
