From looking over the history of these posts, it seems like this is some form of re-direct number where people can call from some place else, and this number shows. I would call telus and complain, in addition to filing a complaint with the CRTC. Of course, getting Telus to do anything is next to impossible because Telus has no clue what customer service means.

I got a call from this number today, it turns out to be my friend in California, US. I believe it's the IP phone gateway.

I just got a call from this #.  The fellow on the other end was telling me my # was selected for a cell phone promotion fro Bell Canada.  Seemed rather fishy, when I told him I already had a phone and didn't need another one...insisted it was absolutely free.  Kept insisting it was free, no strings... I said NO and he continued his spiel.  It was his insistence and the mention of "just taking my contact info" that seemed odd.  I declined the offer and said goodbye.  Tried to reverse look up the # and nothing showed up.

I received a call from this number at 8:00 pm tonight.  I didn't recognize the number so I let it go to the answering machine.  No message was left so I searched the number on the net.

(780) 424-5841 called our residence @2119 hrs. Shows up as PRIVATE. Not home, so no one answered call. Over the past 6/7 years have received allot of calls from this number. We usually never answer calls that are PRIVATE or Unknown Name or number. FYI

This number, (780) 424-5841, has called me 3 times today. When I finally answered it was BBC or something marketing, looking to do some kind of survey. They knew they were calling a cell phone, asked them how they obtained the number, was told it was on the computer, asked her how the computer gets the number. Said she didn't know but could ask her supervisor. Asked her to please remove my number from her list and she said
"Since you said list, we can remove it from the list"
Wtf....
