I just got a call from this number. It was a foreign voice with a strong accent. She asked it I had a computer. Then said she was calling from "Windows ____" [couldn't understand the 2nd word] and wanted to let me know they were getting a message from my computer that it was being infected and was going to crash. She continued on, but I couldn't understand what else she was saying, so just said goodbye.
This is actually some local switchboard that re-routes international calls. I get calls from a friend who is in South Africa right now and it shows up on the call display as a local call from 480-9170.
So the number itself is harmless, however, people calling through it might not be.
The number was rented out by Bell Canada to a third party. They tell you that you have won something and to press 1. They are just trying to sell you something. The last two times that they called me and I got a human on the other end I gave them a blast from a whistle. Funny, no more calls.
I got a call from this #, they said they were UPS, and that I had outstanding charges from the Canadian Revenue for an international package, they left an 866-836-4875 # to call back. The scary part is the invoice # they used is from an old package that was sent almost a full year ago. I spoke with UPS and they are now aware of the situation.
