UCM nodes not getting added for MRA in Expressway-C

Hello

I am trying to setup my collaboration lab. I stuck with a configuration in Expressway-C where I am unable to add UCM nodes under UC configurations for MRA. IM&P and unity connection nodes were added without any issues.

Not sure what am I missing. Below is the message that pops up when I try adding the UCM nodes.

Can someone help me with this?

This is resolved after adding the Root CA certificate for Expressway-C as CallManager-trust in CUCM.

It was one of the recommended steps during deployment, which I had missed initially.

Cheers!

If you were to have the same CA sign the certificates for both CM and Exprw C, as would be the recommended way, this would have been already fulfilled.

This is actually a mandatory requirement, not a recommendation as you put it.
