j ai recu plusieurs appels de (613) 599-1500 et bell canada me facture les long distance

ceci est carrément une fraude.

I think this is a free phone service called happy jack or magic jack or something - people dial into it and then get cheap long distance. Just got a call from my gf that way and didn't recognize the number at first.

I have a new cell phone and didn't give my phone number to anyone yet but I got this call yesterday at 12.05 am. No idea who it is.

This seems to be a logal dial-out hub number for a long distance carrier (Sprint or AT&T?).  I got calls from that number coming from branch offices within my company located in the USA.  The calls I got were legit so, this isn't necessarily a scam.

This is the number of the Ottawa area Rogers Cellular switch. It is wrong Caller ID info.The wrong caller id you're getting would be the mobile telephone switches' aliased phone number being passed instead of the caller id, often called "pseudo ANI" (Automatic Number Identification). Cell phones calling toll free numbers, or toll free numbers calling cell phones, or other toll free numbers will get pseudo ANI. This is always the case with mobile and toll free numbers, and it has been this way since the inception of Caller ID in the mid-1990's. There is no way around this as it's set at the mobile carrier's or the toll free's origination/terminating end. The reasoning behind this is unclear, but we would assume it would have something to do with an grandfathered policy of maintaining cell phone # privacy.
