Aha!  That would make sense.  We ordered the PRI a while back for a new
office space, but construction was delayed, and it has been sitting idle for
more than a month.

Wow, a wealth of information!  Thanks, Rich, for all the dialplan and echo
cancel stuff.   I certainly would not have thought to cover invalid DID'd or
outbound CallerID!  This will save me a GREAT deal of time (which is
suddenly a huge premium for me).

Thanks,
