If you could tell us a bit more about your deployment, what components are involved, what
software versions are used, how does the exact call scanario look like.
If you do not feel that you get a proper answer and you have a cisco service contract consider
escalating the case as a Serivce request (you can do that with the menu on the right top) to Cisco TAC.
Any how please keep us updated what the issue was and how you solved it.
