Solved: Connecting CUCM 8 with CUCME

Jonn cos · ‎01-16-2011

Hi all experts.

I need to connect CUCM v8 with CUCME (2821 running CUCME v7). What protocol shall i use ? MGCP/H323/SIP ?

Kindly guide me

My answer is SIP although others may disagree. MGCP is not a peer-to-peer protocol. H.323 would require you to deal with the ECS vs. H.450 issues.

I'd recommend you to read this and then with that info choose the one that you consider is best for your deployment:

Interoperability of Unified CM and Unified CM Express

My personal preference is to use H323
