Cluster over WAN with NAT between servers

Hi !


A CUCM 7.x cluster exists today as Centralized Call Processing, with one Pub and 2 Subs all at the same site. We need to move the cluster to another location AND to another network, on a phased project. During this migration, it would look like a Cluster over WAN deployment, with a piece of the core already migrated and a piece on the existing site. The problem is that this cluster is from a company A that has been acquired by company B, and the moving of the cluster involves re-addressing of the servers.

The networks A and B can see each other through static NAT entries. I know that an IP phone can reach a subscriber through NAT, with a certain feature on the NAT router, I think.


But what about the communication between Publisher at network A and the Subscriber at network B? Can they establish database connection and all ICCS traffic with a NAT between them ?


Cheers !

Cluster members cannot have NAT or other hindrances in between.


If necessary, configure a proper VPN.
