I realize this is probably something one learns in Telco 101, which I
haven't taken, but if CNID == Caller ID, wouldn't ANI be *more* useful?

Or does CNID report the number regardless of Caller-ID blocking on PRI

(I'm assuming that CNID == standard Caller-ID as it appears on POTS, and
that ANI == the special service that 800-lines get that *always* reports
the number, regardless of blocking..if I'm wrong, I'll accept the LART.)
