Yes, it's a scammer or someone playing games.  I get a call from this number (originating, I think, in Itasca, IL) around 1 p.m. every day, day in and day out.  The guy asks for a person who I don't know but who apparently had our phone number 10 years or more ago. And every day it's the SAME guy calling!  I recognize his voice now.  He always asks for this person, and at first I told him (the caller) to go away.  He doesn't go away.  Now I just hang up or allow my voice mail to field the call.  Never any message but the guy keeps calling every day.  He claims to be with the Illinois Coalition of Police or something (lol) and I wonder if he simply likes to annoy people.  What idiot would call day after day after endless day and get a hang up?  And then keep calling?  People like this ought to be fined and tossed into jail for a while.  Maybe their little games would end.
