Service unavailable after one second
Hello,

when i place a call, after one beep (about one second) the T48G shows me a error message: Service unavailable and it gives me a busy tone.

If the other person, i call, takes the call directly, i can speak with him.
But if not, it is not possible to establish the call.

Thanks for help,
Daniel
