What does 'Permission Denied (5)' mean on my Nortel 1230 IP Phone and how to solve it?

The 'Permission Denied (5)' error on your Nortel IP Phone can occur if an incorrect User ID was entered, so make sure you enter the correct User ID. It might also mean that the remote IP Phone does not have VOUA Class of Service. If this is the case, notify your system administrator.
