calls, I answer, ever who this hangs up every time, called back, it was a voicemail that said "you've reached an invalid pager".  Ever who this needs to quit calling. I am on the no not call list, but the calls keep on coming

same thing happened to me, why????????????  can these be reported as my number is on the do not call list??

Called, hung up.  When I called back, it was a voicemail that said "you've reached an invalid pager".  Might be harvesting phone numbers, as it is clearly not a pager.
