I have CCM512 and CUPS 103 installed and configured as per the deployment guide.
I have installed Unified Personal Communicator 188.8.131.5238 and can successfully log in and search/add contacts to groups (so LDAP is working). Desktop phone call control also works as well as the Softphone.
The problem is that non-communicator users/phones (or communicator users not logged in) always show as offline.
If 2 x Users run the Communicator then they can see each others presence but no-one elses.
Phone Messenger via the Services on the IP Phones works fine and I can see the presence as you would expect.
The CUPS Troubleshooter checks out 100%.
I have sniffed the traffic between CCM/CUPS and the PCs and SIP Open/Closed notifications are arriving at the PC running Communicator and being acknowledged.
Just to annoy me the monitored Users icon on the communicator refreshes/flickers when the monitored users phone is taken on and off hook.
Has anyone seen this before? It is driving me nuts.
