I will have DID on the PRI.  I have not tried chanting "DNIS"; I'll try
that start of business Monday.  The DID is the root of all my problems;
I want 20 DID numbers sent to that ISDN/BRI interface, and have the ISDN
TA know which DID number made that line ring.

The problem is not supplying it over the PRI; that they can do.  The
problem is that once I split a BRI off teh PRI, then what happens to the
DID number?  That's what no one can tell me.
