I have a CS1000M (opt81c) with 3.0. When I dial the Miran access code it starts the prompt but then cuts off and rings busy. I have reset the card and can access the config through the card. I have printed out the route and it is the same as my other routes that work fine. All of the messages play fine and everything else is normal but the access code to the menu to listen to the recordings. Any ideas?
