We are running OCS 2007 R2, and recently our voicemail system has gotten a little wonky. After hours, the message plays, and the user can select from our directory as prompted, but for some reason, when they pick the second option for the general voicemail box, it's dead air. The call never disconnects though, and users will have to hang up themselves. I tested this by trying to stop the processes associated with the server, and the moment I do, the call drops.
I'm not very familiar with this part of OCS, does anyone have any ideas on where I can look?
