My sister is overseas to visit my parents for a couple of weeks and , every time she calls, this number appears on my call display. When I asked her she had no idea but said that she was using a calling card.

Here's some info I found....This is one of some generic numbers (also (416) 252-0153..etc) used by Skype's gateway for making pc to phone calls. Anyone using Skype service (usually in GTA)for such calling might display this on your caller ID.

I just received a call on my office number...it was from Signature Training Canada...but the number they left to call back was an 866 number.

OK, so first the company providing service for that number is Allstream (waiting for them to call me back). I have already gotten RBC involved due to the fact that they are committing fraud. I have also gotten the RCMP Fraud department involved as well and encourage the rest of you to do the same by calling 1-+1 888-495-8501 or info @ phonebusters.com
I also encourage you to involve whatever company they may have claimed to be representing as that is a good way to get something done about it, Bell does not appreciate this sort of false representation and have the money and lawuers to do something about it.
If they call you again immediately after the call dial *57 to activate a call trace, then about 2 - 3 days after, call your local police department with the time and date and they will give you all the info you need about that number which you can then use to file a report with them (I was unable to trace my call because I didn't know about all this)
I have a theory that this info may have been gained through a contest ballot such as the ones I filled out at a bridal show at the Metro Toronto Convention Center 2 years ago. Plus the RCMP fraud phone department is having a major issue with people getting those calls saying they have won a trip and whatnot. I usually get those from filling out contest ballots... $200 to go to Mexico! Yeah right.
P.S. Use this sight as reference when reporting these people to companies and/or police.
Hope this helped... just don't give up, that's how they win... people to lazy to do something about it. What they are doing is illegal and wrong.

This company is supposedly called Noah Home Services. ?They call me at least 5 times per wk!  I spoke with a manager to ask them to stop calling & he promptly hung up on me. They give phony numbers when I ask to call them back.  Also the number that comes up on call display is a phony number too!

somebody jut called with that caller ID...he said we had just wopn a free package..I didn't let him go further than that..."Click"...goodbyeeeeeeeee...scam artist for sure...they would know addresses specially if you are listed on 411.com /411.ca/Canada 411....
