You can hang a caller ID box on your line and watch the kind of crap that comes in. Usually they try to make a "real" phone number, only it's in an area code you've never heard of. But some of them give shit like "123-4567" or just "1" or "---------------" for the phone number. Also fun are the ones that set the name to "NEW YORK" or "FLORDIA". I can just imagine Cletus from the Simpsons saying "Well gawwwawleee we've got us a call from NOO YARK!"
The insidious ones are like mentioned in TFS, where they use an actual number that's not theirs, often picked at random. I heard of one case where they used the phone number of some little old lady in Boston, who of course got all the backscatter from the phone spammers.
And of course most people on the receiving end of the junk calls have no clue that the CNID could ever possibly lie to them.
