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've been getting calls from this number on Nov. 27,2010 & called four times at my work number after hours.  Again on Nov. 30, 2010 two times again after hours at my work number.  No message is ever left.  Called the number and a recording came on saying the number you have dialed is not in service.  So i'm guessing this is a scam.

(780) 424-5841
These guys called my cell asking whose phone it was and all kinds of questions- told them off and hung up.

I got called at 5:55pm Friday November 6th but I didn't answer it as I didn't recognize the number.  I've tried reverse look up but nothing comes up.  Luckily I've only been called the one time.

I too, have had the same calls for the 3 weeks, comes up a +1 866-270-3021,and or
something very similar.
approx over 35 calls in the last week.

This number calls me daily, when I answer, I get loud beeps in my ear.  But I get a lot of phone calls from strange #'s that do that.
Another Famous # is (780) 443-1480 with the name "Digtl contct" But the # alway changes.  I get these calls all hours of the night, and day.  I feel harassed.
