[cisco-voip] ISDN q921 error

I agree with Kris,
It sounds like the communication to CallManager is broken. Have you 
tried stopping and restarting the MGCP process? Sometimes that can 
kick the d-channel into gear.

I'm not very familiar with qsig trunking so I could be way off buIt sounds
like d-channel backhaul is not working.

If you do a show ccm-manager, are you registered to the call agent?
