I get calls from this number a few times a week.  No one answers when I say hello and I too have tried to call it back an i says it is not a "working" number.  Comes up on caller id as "New York".

This  person(s) been calling my number all week and rwice on weds.
(Shows up on my caller id)
When you try to call it back it says its not a "work" number.
My 1st guess its a scammer!
