I set up CUPS with a NFR kit for the very first time and have a few questions. LDAP is enabled so I was able to import users into CUPC. However, in the 'end user' page of CUPS, it shows 'No Audio' and 'No Video' for my CUPC although IM is enabled and it's associated with the desk/soft phone DN. As for the desk phone, it shows 'Audio enabled' and the DN is associated.
You should see the same in deskphone mode too if a call comes in. You should also get a "phone off-hook" pop-up when you lift your handset in deskphone mode.
What versions of CUPS/CUPC/CUCM are you using??
I am running CUPS/CUPC/CUCM 7 and I see the same thing in the presence veiwer...however I am able to make video calls.
I do know that the Presence Viewer has issues.
