I got a call from this number.  I missed the call, and when I checked my voicemail I had just a hang up.  I tried calling the number back, and I got a busy signal.

Receied a called to my 416 area code cell ph number and just heard a 'beep, beep' response when I answered. The 'beep, beep' could be a fax machine.

yeah calls and then you hear these long beeping noises

Received a call from this number and when I picked up there was a ring tone.  Believe they got my number from a ficticious add on Facebook that seemingly appears to represent Dell computers.  It is the only time I gave my cell number out, except for family. Unfortunately I didn't realize until after-the-fact that it was not Dell that I was giving the number to.

yeah, i got a missed call from this number too! (647) 722-1121.. i called back, but line is busy or sometimes when it rings, it hungs up. this is so stupid!
