its a Skype number. i get a lot of Skype calls from people, and this number shows up so often i just saved it as Skype in my phone. I could be anyone trying to use VOIP, because when they call from the internet it has to go through a local number so it is given one that is not assigned, i think. either way, i get Skype calls from this number along with a few other 613 numbers, as well as other random numbers like 0000123456, haha.

I received a call from this number Oct. 12, 2007. Same result: I answered it and there was nothing on the line. I called back and got a 'not in service' message.

Called the home and when answered it sounded like someone was listening and then hung up

I got two calls from this number today.  The first at 7h03pm.  Called back and like many others, got the "number is not in service" message.  Got another call at 7h51pm.  Answered it and it was Penny Collenette's campaign asking for my vote.  From what I've read above, sounds like this number is being used by different services at different times.  This info will probably not help anyone looking to find out who's calling them after the election as I'm guessing the number will probably be taken over some other service afterwards.

I think this is a number long distance carriers use. Here's the deal, I have a vonage line and I wanted to test its call forwarding capability while I was overseas. I called the vonage line which call forwarded to my local cell phone, but the number showed on my cell phone (and vonage call display) showed (613) 232-7437.

well they called me and they said that it was from scotiabank wanting to talk to my mom.
