[cisco-voip] Expressway C&E with multiple CUCM clusters

[Kevin Przybylowski]

Correct.  We’re deploying one as we speak and the big caveat – that they all service the same domain.

x8.5 allows for multi-deployments.  From what I can tell, it will only work if each cucm/IM&P cluster services a single domain.

Multiple deployments for partitioning mobile and remote access to Unified Communications services This release introduces the concept of "deployments" to the Expressway. A deployment is an abstract boundary used to enclose a domain and one or more Unified Communications service providers, such as Unified CM, Cisco Unity Connection, and IM and Presence Service nodes. The purpose of multiple deployments is to partition the Unified Communications services available to mobile and remote access (MRA) users. This enables different subsets of MRA users to access different sets of services over the same Expressway pair. We recommend that you do not exceed 10 deployments. For example, consider an implementation of two sets of Unified Communications infrastructure to provide a live MRA environment and a staging environment, respectively. This implementation might also require an isolated environment for sensitive communications.

Hey all,

Wondering if anyone has done expressway c&e with multiple clusters. Am I correct to assume it's a 1:1 relationship (1 C&E to 1 CUCM cluster) or is there a way to use 1 C&E with multiple CUCM clusters?

Thanks in advance!
