Received a call from this number on 8/26/14 at 8:14 p.m. Central Time.  A woman said "hello" several times, with noise in the background that sounded like a call center.  I said, "Who is this calling?  You sound like you are in a call center."  The woman hung up.

missed a call today from this number, no vm, checking here, wanting to contribute to stop spam calls

Called at around 4pm PST today and did not leave message. Caller ID said call was from "MN, USA"

Missed the first call and attempted to call back, however after 5-6 rings it said the number was either disconnected or moved to a different area code

I got two calls from this number on 9-11-14.  I missed the first call and when I tried to call it back I got the same message as "Confused".  The second call came a couple of hours later. Obvious boiler room, said I won a sweepstakes of some kind, and when she gave me the Tom Hopkins close, I just said I had another call (I actually was on another call) and hung up.  Haven't heard back from them today.  I'm hearing from some friends on Facebook that there is an advance fee telemarketing scam for vacations going on now.
