Our sales team is setup with DN's and then remote destinations and remote destination profiles to ring their mobile phones. This works for most, but on occasion I have seen this setup stop working like today for one user. We call his DN and I receive a fast busy, if I set the forward unregistered internal/external to on this is the at least allows for VM to pickup. Any thoughts on why this works in some cases but not all? What's the best practice in handling scenarios such as this, I can't do a CTI since that does not allow for shared lines, correct?
