Is the called number onnet or offnet?

Can you send a debug isdn q931 from the gateway?  CM needs to receive a
disconnect message with a progress indicator Information Element to know
to cut through audio and receive the busy tone from the destination.

I have an issue with one of my remote sites where they are not getting a
busy tone when they dial a number that is engaged, instead of saying
Busy the phone display says Call Proceed and it goes silent.

Not quite sure how long this has not been working for, can anyone help
with this we are running 4.1(3) with H323 gateways.
