That's what I said wasn't it? ;-)

Provided your PRI is set up correctly, you should have a one way speech
patch from called party to calling party upon issuance of an ACCEPT. I
believe it was done this way to allow PBXs to generate ring back, busy etc,
thus offloading the central office switches at either end. This is in
contrast to the European way of doing things where call progress indicators
are generated at the local exchange (for in-country calls at least).

This means that you should be able to generate "number not in service" or
"number changed" announcements to callers without answer supervision, so
that the caller is not charged for the call (which is right, you shouldn't
be charged for such announcements).
