[IP] more on VoIP hacks gut Caller I.D.

[David Farber <dave@farber.net>]

And CallerID DOES NOT get blocked for any 800 like services. So most of 
the advertised use is bogus

This happens with landlines as well -- CallerID blocking does not
provide anonymity (depends who you call). For cell phones, I know
by experience that a CallerID blocked cell phone can, notheless,
advertise the number and the *name* of the caller to a common
user who has the proper, off-the-shelf, equipment.
