[cisco-voip] Changing CUCM System>Server from IP to FQDN

[Ryan Ratliff (rratliff)]

The doc I have is a draft version so may be subject to change.

What is directing you to use the FQDN for helping jabber validate certs? I don't see anything perusing the server setup guide or install guide for 9.6.

What document is that?

The reason for changing the system>server to fqdn is more because of the Jabber for Windows certificate validation process than for CE.

That being said, if Jabber wants FQDN and Collab Edge doesn't, we will have a problem.

Using FQDN in System->Server on UCM is specifically not supported in the Collab Edge deployment guide I'm looking at.

It's ok to use a hostname there but it must be resolvable by the Expressway-C (and the phones of course).

We were but it interferes with EMCC.  The phone only does DNS lookups for the domain it is assigned so we switched back to IP addreses.

Is anyone using CUCM deployments where they set the System>Server value to the FQDN of the CUCM nodes ?

I'm in the process of deploying Jabber for Windows 9.6+ with Collaboration Edge, and there are requirements around certificate validation that seem to require the CUCM System>Server value set to a FQDN.

I'm concerned around making this change and curious if others are using FQDN.
