Just a silent or hangup call.

Just received a call this morning from this number.  I do NOT answer any calls where the ID is "Blocked", "Unknown", "Unavailable", Anonymous" or "Out Of Area" or I don't recognize the caller ID.  The caller ID on this call was "OTTAWA   ON", no name and then the number.  Since we know people in Ottawa, I called the number back twice and both times I received the, "This Number Is Not In Service". "Please Check The Number and Dial Again"!  From what has been reported here, I see that it s a scam.

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.

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

They keep calling me. I say "Hello", they say nothing. they annoy me.

I got a call from this number.  first there was a recorded message saying that President Obama wants us to re-negotiate our mortgage then had options to press.  I pressed one and a girl on the line asked me if I was interested--I told her I had no idea who she was and she hung up.  I'm worried that this is a scam and others might be pulled into it.
