Re: ISDN PRI Voice E1

AL - amber means you got an ALarm, because router got no signal.

AL got cleared after putting framing NO-CRC4 under controller. but the attached error occured when making calls.

Re: ISDN PRI Voice E1

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.

Re: ISDN PRI Voice E1

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.
