Also got a phone call from 708-434-4074 on Tuesday, 5/19/09 at 1:25PM.  Had left phone in purse & all I had was the message about the call having come in from that number.  No message, either.  
Who are these people?

On July 28, 2009 I received a call from this numvber, 708-434-4074, at 7:46PM.  On July 29, 2009 I received another call from this number, at 7:32PM,  As I didn't answer the call either time (My phone was also in my purse.) I looked and the caller ID says "(No Name)".  No message was left.
I would LOVe to know who these people are!

Got a call from this number at 4:15PM on a Sunday, didn't answer, left no message.  Again at noon-ish on Monday.  I'm at work so obviously I didn't answer, again no message.
