It did but I was getting no audio on those channels so I removed them in 
hopes that the telco would not try to send call to those channels as a 
temporary fix while I track down the cause of the problem.  How can I 
just busyout those channels (48,72,96) so that calls are not sent to 
them from Global Crossing?

I have a DS3 and seven servers running NFAS, I do not care about the 3 
lost channels per trunkgroup but I do care about customers calling in 
and getting dead air. 
Global Crossing charges us $100 per D chan so NFAS is saving us alot of 
money.

Thanks
