Re: (ASCEND) DOV headaches

[Jason Nealis <nealis@babylon.erols.com>]

I had the same issues here going through a couple of local CO's, What was
happening was the call was coming in to hot and teh CO would PAD the
call down thus you start getting the ton's of CRC errors. It was BA way
of stoping me from doing DOV. 

Try calling through a LD company and see if the call works.
