Suddenly our incomming ISDN calls stopped to work. In the caller side I can hear a long ringtone and after a while I receive a busy signal; on the called side nothing happens(no ringing)
I attached the debug output (q921,q931) can anyoane help me with an idea what is happening?
As I saw the voice gateway is disconnected by the telco, I looked after the cause code 0x829A but it's not realy clear for me the meaning of the: The destination is able to accept the call. However, the destination rejects the call because the call is not assigned to a user.
