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 got a call from (780) 424-5841 at 6:15pm the other evening.  The person on the other end was a male, and it sounded like his voice was computer altered to disguise his identity.  He greeted me by name so he obviously knew who he was trying to call. He claimed he was from an alarm system company, and offered me a free wireless alarm system as an Easter special.  When I said I was not interested, he asked if it was because I already had an alarm system in my home.  I told him again that I was not interested and hung up.  I seemed like he was fishing to figure out if my home was protected, and if not it could become a target for breaking and entering.  I tried calling the number back, but all I got was the message "this number is not in use". After reading the other postings, I am definitely going to report the call to the authorities.

No one on the other end....Maybe a wrong Number ???

that number is (780) 424-5841

Hey even I have recently been getting calls from this (780) 424-5841 number and what's strange is that guy even knows my name and lot of other things. When I call back it's always engaged. Plz let's complain to the authorities about this number

This number is a spoof.  The call is probably coming from a VOIP line somewhere outside Canada that is being used for scams.  Just fart into the phone and hang up.
