Now, now, Ron... let's be accurate: I stated that it couldn't be
spoofed at the casual subscriber level in the fashion people were
asserting.  I _never_ asserted that there was _no_ way to spoof it, and
in fact, in at least one of my posts, I noted that there were a couple
of specific, if difficult, approaches to the problem.

See above.  :-)

And in the case of cellco's, it usually ignorance or stupidity that
gives you the wrong number.  It's also worth noting that even when a
cellco screws this up, _the number you get is *still* accurate, it's
just not what you expect._

This isn't really spoofing.  Spoofing is "I'm Jay, and I want it to
look likr Bill is placing these threatening phone calls, so I'll put
his phone number on their box instead of mine".

: So combining our wits we can trace back how a telemarketer may produce

: answer the cell phone...

If what she asserts is happeninga, actually is... and if it _is_, one
call to their chief engineer ought to clear it up.  The FCC takes a dim
view.

: Now, according to Ms. Mouse, anybody he calls using his cellphone will

: above).

: And   that's  how it *can*  be   done  (in BellAtlantic-served areas).
: Probably one of SEVERAL ways, too.

See above, again.  :-)

: So everything is possible.  Even getting "PRIVATE" callers (*67ers) is
: possible with a little creativity...

Getting the ID of a call marked private?  Yeah, subvert the switch.
