CM 3.1.2, just upgraded from MM 3.0 to MM 5.2.1. Its a toss up as to whether this is a CM or MM problem. The transfer to voicemail feature access code was heavily used by people with bridged appearances of other people's phones. They answer a call and if the caller wants to leave a message they would press transfer, our fac for transfer to voicemail, then transfer. After the upgrade it opens the callers voicemail instead of the recipient. It does not go to the greeting, it transfers to the extension.
