I have an issue where, when a user places/receives a call their MOC status shows them as "on a call", 99% of the time when they end the call the MOC status changes back to what ever is was set to, i.e. Available.
The 1% of the time is will stay "in a call".
Now I have managed to trace a call from the CUP server and when the status updated correctly I can see a SIP message "ConnectionClearedEvent", however when the status does NOT change back there is no "ConnectionClearedEvent" in the SIPProxy trace file.
So I am assuimg that some thing between CUCM and CUP is failing everynow and again.
I am having a mental black and need to be pointed to the CUCM process that would pass the information to the CUP server.
Any other help would be appreciated too..
