I got a call from 416-293-6589, but didn't answer it since I didn't recognize the number.  There was no identifying name displayed on Call Display either.  The caller left a voicemail which sounded like he was calling from a telemarketing boiler room (loud room, lots of background voices), and said, "Hello?  Hello?  Hello?" etc. for a full minute.  Intrigued by such a detailed message, I called the number back, but got the phone company's automated, "This call cannot be completed as dialled.  This is a recording."
Better luck next time, scammer!
