"Jaden Walker" called me from this number, several times.  Said he was from "Premier Concepts".  Heavy acccent, difficult to understand, said I'd won a prize in a raffle.  Listened along for a while just to see what kind of scam he'd lay on me, then got bored and hung up, as he took forever to get to the point.  He spent a lot of time going on and on about how this was legitimate and he would give me his "name and company name" so I'd know he was legit (?) and also that the phone call was being recorded for state and federal review (??) so I should feel very confident in the legitimacy of this call.  He then started talking about how I'd won a flat screen TV, and $2500 cash, and blah blah blah, and then something about a Holiday Inn in Washington DC.  

Seems very similar to calls reported on this website from this number:  630-847-8813

In retrospect I wish I'd toyed with him a little bit, but oh well.
