Last week we updated our callmanager Business Edition 6.1.2 to the latest ES. We had a few problems, but they are solved accept one.
Unity Connection (integrated on the same appliance, because it is a business edition) has IMAP integration so that a user can listen to its voicemail through its mailclient. (in our situation Outlook) The service is stopped in the Unity seriveability. When I start the service, the service starts fine. I can connect to the callmanager at port 143 and Unity Imap responds. As soon as I try to connect with my Outlook client the IMAP service stops.
Maybe someone else has the same problem (solved).
