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

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.

Received several calls from Ontario, CA (613) 216-2172 with no message.  Called back and no company name was given, so I hung up.  Now I'm charged for two international calls to Ontario, Canada, which totaled over $6 with all the taxes and carrier cost recovery fee.It's a scam.

After pick up the phone no talks, When I called back says mesage box is full. so, so aggravating!@#$%^&*

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.

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.
