I also got a call from this number on my cell (647 area code) at 6:19 am Dec. 13th 2007. I live in Toronto ON Canada. I simply thought it was my alarm going off but wouldn't have answered anyway.
I got a call from this number 13.12.07 at 4.27 am (an ungodly hour)and there was no one on the other end. After reading the other posts, I realized that the other 'prank' called I received on 09.12.07 was probably similar in nature. Needless to say, my boyfriend screamed curses into the phone this morning, because there are very few instances when a call at that time is good news.Hopefully we can figure this out.It seems to be hitting North America, as we live in Montreal, Quebec.
