I picked this call up by accident, as I was expecting someone to call.  When I just heard dead silence on the other line, I checked my caller ID and realized it was a dumb telemarketer.

This number has called several times for several days.  Caller ID says "unknown name" then the #. As soon as answering machine kicks in they hang up. I'm on the do not call list, also.  Maybe next time I'll answer & let them know what they can w/obama mortgage plan.

I won't answer if the Caller ID reads "Unavailable," and I don't recognize the area code.  No message left.

It's a scam.  Shows (613) 216-2172 "Ontario" on caller ID.  They are tryomng to get your credit card information.  File an online complaint with the FTC here:

Received a call while driving and there was no one on the other end.  The Caller ID indicates that the origination is in Canada.  I do know that a lot of fraud is now coming out of Canada, targeting people here in the US.  The most often used is by mail and includes a large check that is drawn under a legitimate company name and a phone number in Canada to call to inquire how to get the money... which involves sending money to them for "taxes" on the "winnings"...

Though I have tried to "Call Block" this number through ATT, the service will not allow me to do so!

looks like whomever this is is at it again.....i didn't answer as i knew it was a call from ontario canada....so i called back and a voicemail greeting says the mailbox is full....whatever....obviously whomever this is is up to no good AGAIN!!
