I upgraded my 3300 today from 9.0. I first had to upgrade to 4.0 and then to 4.1. I am having an issue with voice mail. When a user tries to log into voice mail from their extension, they are able to log in and then when they try to play it from the handset they get "The voice message cannot be played because a system error has occured." If you dial the voice mail extension you are able to put in your mailbox and passcode and it works fine. Any suggestions on how to fix this error message if they log into the voice mail via the blinking voice mail button?
