I recently migrated our UC system from 8.6 to 11.5 and that went well enough.
We had not been using CUP or IM&P before, so just installed IM&P Publisher server, so we can start using Jabber clients. And eventually I'll add our VCS/Expressway servers for VPN-less phone access.
I've read the Cisco deployment guides, watched YouTube videos, and more. I think I'm doing everything I need to do. But for days I'm getting stuck with an error when trying to login to the Jabber client, "Cannot communicate with the server".
At one point I was able to successfully login with Jabber, but couldn't make outbound calls. While trying to solve that problem I must have done something, because now I can't login at all.
I'm trying to login to Jabber with advanced settings, Account Type CUCM, Login server manually set to my CUCM Publisher. Username is my ID@domain name (matches IM&P > Presence > Settings > Advanced Configuration > Default Domain). It seems to be authenticating correctly, because if I put in a wrong username or password I get a different error telling me I used the wrong username or password.
I created a lab environment with a CUCM and IMP server and created a basic setup and performed the same IMP and Jabber setup and ran into the same error (no DNS/LDAP in the lab environment)
Below are the configuration setups I went through for the CUCM and IMP servers in our production environment. I did configure the SRV records on our DNS server for .cisco-uds (pointing to CUCM Publisher) and .cuplogin (pointing to IMP Publisher).
