I am running CUCM 6.1, CUPs 6. My CUPC clients are having problems. They authenticate ok, can talk to a desk phone OK, havent setup MP or Unified Comm yet. However, under the "server health" it cannot connect to presence. The error is "failed to connect" no servers configured. The troubleshooting on CUPs shows no issues. I have the Presence server specified on CUCM.
In the description type in All
in the address pattern type in all (small caps)
Do this for outgoing as well.
Something in the SIP trunk. Restart your SIP proxy service. Also check to make sure you have add in the incoming and outgoing ACLs to "all" so it accepts and sends out the SIP messages By default this is turned to deny. It's wonderful Cisco documentation that stinks.
Check your "troubleshooter" on the CUPS server to make sure everything is ok.
CTI is working, because you can control the phone
Also check the following:
All Presence users have digested credentials. (anything filled in works, they will never use it)
Line associated to CUCM end users. If this in not selected, then presence will not show of the person.
Try changing all your SIP trunk settings to IP address only.
If have a subscriber server in Presence, shut it down and test with one server first.
Hope this helps
