what is the error message ? also please send the output of debug isdn q931 too .

There is no error in your display. If you are concerned about the up/up spoofing, then that is normal behavior. The D-channel is kept up spoofing to keep the ISDN switch and the router talking..Do you still have an error or an issue??
