I have a weird situation with one of our customers. When reception tries to do a direct to VM transfer, callers end up hitting the Auto attendant instead. They don't reach the mailbox and end up having to call back as they do not know the extension number. Reception tries again and it usually works. This problem is intermittent and doesn't happen very often. Has anyone ever run in to this? If so, why does it happen and how do you fix it?
