port 5222 is not close on the uccx finesse.
From What are You testing to make the connection ( program language )
Strangely enough, nmap detects port 5222 as not open:
Looking back in old notes from a year ago it looks like the XMPP port utilisation was something that was broken temporarily on CCX by a patch and then corrected again in a subsequent one. So, I stand corrected, and yes it does make sense provided it's now working as documented; you should have the ability to revert back to 5222.
