[cisco-voip] Jabber IM service Issue

Fri Dec 22 11:18:10 EST 2017

I don't see any connection attempts on port 5222 in the logs.  Might want
to enable tcpdump on the Diagnostic Logging page and try again.

Also try https://cway.cisco.com/tools/CollaborationSolutionsAnalyzer/ and
go to CollabEdge validator.  It will test against your domain with a
username/password.  You can also put the logs in there and it may show you
what is going on as well.
