asterisk users - Mar 2005 - Sip 400 bad request - broadvoice error

I have searched the list and cannot find a sip 400 solution posted that
solves my problem.  If anyone has any thoughts or suggestions on the
following I would greatly appreciate it.

I didn't have this error before Broadvoice made their changes this
weekend.  Now when I make a call it connects but, I cannot hear anything
on the other end... 


The full message I have is:
