Hi, something seems wrong with the circuits, please send output of "show controllers e1" and "show isdn status".

Hi, you said you got four channels for test, but your pri-group is configured with 31. The connected switch is telling you that exactly.

Shutdown voice-port, remove pri-group, reconfigure it with timeslots 1-4 and you should be going.

Now you have to ask your telco why the call is not accepted on channel 4. Sometime they say they have done everything, just to find isn't quite the case.
