Who called from 3123806711

Got a call from 312 380 6711

Did not leave a message

Background sounded like a call center. Hung up after my, "Hello."

Call came from Chicago to Kansas at 19:11 hours CDT on 6-5-11. Call not answered and no message left. Other sites report this is from a cancer donation pitch for funds outfit.

This is from charity solicitation service.  Hung up after a hello.

I also received a call from this number.  I let it ring through and no message was left.  I tried redialing the number and I got nothing, not even a ring.  Interesting.  95 percent of the calls I get on my home number these days are from someone wanting money from me.
