No it's not.  Sprint, in the southwest, converted presented CNID to ANI
and sent it along.  Check the telecom archives.  But this isn't germane.

Indeed.  But that's not on point, either.

I understand your point, but I'm of two minds on this, as I am on the
current ATM password fracas, and for the same reasons.

Indeed it is.

Oh yeah, they can ask you *useful* questions.  Like your mother's
maiden name.  And your SSN.  :-)

Precisely.  You're saying that "not spoofing caller ID" is not part of
the American Social Contract, then?

The need to send CNID not your own for non-nefarious purposes (see the
HP pretexting scam, and if you *don't* think that's going to dribble
over into telemarketers sending fake CNID, TCPA notwithstanding,
then you're nuts) is rare enough that I have no problem requiring the
telcos to get a signed agreement from clients to turn off the filters.

But gratuituously making easy something that very few people have a
legitimate need to do, which undermines something that -- even if you
do only make the resaonable assumption that you know which phone, and
not which person, is calling -- is useful and productive... is probably
a Bad Idea.  Full disclosure notwithstanding.
