....which makes me wonder how this can be done?
A phone number calls my line, and when you call back, you get a "not in service" message?

I just got a call from this number as well & he said he was from TD bank asking if i have done any banking or consulted with anyone at a branch.. was a yes or no question, after i said no, he hung up...

Do u guys deal with fido? I believe this number belongs to them, as i recieved a call from this number and it was a Fido supervisor...

I receive calls from this number at my work place almost everyday. When I answer nobody speaks. and after a few second of silence the line gets disconnected. When I call back it plays " The number you've reached is not in service - this is s recording". I wonder how this type of automated calls pass through our exchange and reach my extention. Ususally, if someone wants to reach me at work he has to dial the exchange and then dial an extension. Is it possible to follow these steps through automated process?

By the way, I don't owe money to anyone and I don't use Fido or Rogers service. But the skype incoming number is generally ends with 0000. I've a friend who calls me regularly from Skype and I see different numbers all ends with 0000.

Does anyone have any clue about this spammer?
