Wait, is this a Jabber user or a Jibber-jabber user? I'm getting mixed signals here. Either way, let's hope they trust the Expressway-E certificate, or else they'll be stuck in a Jibber-jabber loop!

I wonder if the Expressway-E certificate was generated using a self-signed CA. If so, that could be the root of the problem. But yeah, option B seems like the way to go.

Creating a new CSR with updated SAN information could work, but it might be overkill. Option B looks like the most straightforward solution.

Hmm, I'm not sure about that. Changing the domain name or the FQDN of the Expressway doesn't seem like the right solution here.

I think B is the correct answer. The Expressway-E certificate should include the Cisco Unified Communications Manager registration domain as a SAN to ensure proper trust verification.

That makes sense, it's important for the certificate to have all the necessary information for proper trust verification.

I'm not sure about option B. I think creating a new CSR with new information on the SAN field (option A) might also work. It's worth considering all options before making a decision.
