I've got a problem with the OCS2007. Calling from Communicator to Communicator works fine here and calling voicemail from Communicator also works fine. Callling to Communicator from outside also works. Only calling voicemail from outside doesn't work. If I click forward calls to voicemail in the Communicator that doesn't work, too. In the 2 cases i only get a busy, if i try to call the voicemail. Has anybody an idea what causes this problem? If you need any logs or something, please tell me.
