I reported this to the FCC complaint section which is separate from the Do Not Call Registry.  Coogle FCC Telephone Complaint.  They take this seriously and do follow up.  Register your complaint. There is power in numbers

I keep receiving this call. I called it back and it says the number is disconnected.Ottawa  ON  (613) 216-2172 appears on my caller ID

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!

didn't answer when i picked up.  afterwards,  i accidentally pressed to the number to call back.  turns out, they're some sort of loan modification co.

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!!

Call came @ 2:11 PM EDT on 08.14.2009 -- caller ID read OTTAWAHULL, ON, apparently originating in Canada. If I don't recognize the name or number on the caller ID whomever is calling is wasting their time because I don't answer.  I've been on the do not call list since day one but that list means absolutely nothing because it hasn't stopped the calls.
