Received a call from this number today 10/22/07 at 6:57 PM on my cell phone. I did not take the call. I went to AnyWho and tried reverse look-up, but there was no information on that number? How do you find out who this is and if it is a legitimate call? I didn't want to be one of those people suckered into taking a call from somewhere outside the U.S. and then get a huge phone bill.
