Welcome to this customer Community. I'm not sure what you mean, so perhaps best to go back a bit! Are you new to Sky broadband/landline? If so, what was your activation date, and is your phone plugged into your broadband Hub? It won't work from a wall socket. Do you have a black broadband Hub? Or a white one? If it's the black one, is the Voice light on the front panel lit? Amber? Or Green?
