Yep. Despite being on the Do Not Call list I was getting a number of marketing calls from various area codes. I complained and was told it was determined these calls were being generated over a VOIP line based in Bulgaria. Out of their jurisdiction so I was out of luck.
This is why I keep my cell # and work # private, and I still get a few on my cell.
My home # has been taken over by these.
To get sale items here in many stores they demand your phone #, in fact radio shack gave me a free set of $12 earbuds for my home phone #.
Fortunately I love my phone/answering machine system /built-in speakerphone wireless set. Makes it easy to screen calls(most of time I don't pick it up then just delete messages).
And as I said, my caller ID comes on on my TV sets too.
