Connect multiple CUCM Clusters to centralized CMS Cluster

[steinbrunnerj]

Hi all,

we would like to connect several CUCM Clusters to a centralized CMS Cluster with configured SIP Trunks from each CUCM to the call bridges.

In the "Deployments with Cisco Unified Communications Manager" guide in Appendix A I found some info about the deployment model with SME between CUCM clusters and CMS Cluster.

My question now is, do I need a SME in the middle or can I connect my CUCM cluster SIP trunks  directly to the CMS call bridges. Are there any constraints and limitations in such a setup?

Are there any official documents about such deployment models available?

Thanks

Best regards,

Jörg

Did you ever get resolution to this question? I have a similar requirement and am looking for answers.

Hi,

no, I did not really get an response but in the end we tried it and it works. Important is, that you use unique Conference Bridge Prefixes when configuring CMS Conference Bridge in CUCM. 

Best regards,
