Call from (416) 555-7777 (unused number) then hangup.
Caller id was "sialk.ca"

The CRTC will be involved next time.
My number is on the "do not call" list.

I am from Toronto, Ontario, Canada which is actually the city where the area code is 416. However, as a long time resident of Toronto I know that 555 is NOT A LEGITIMATE 2nd 3 digits! This is spam! For sure! Let me tell you this: When a commercial is made for air/posting around here and they need a fake number they use 416-555-xxxx as the number because NOBODY'S SECOND 3 DIGITS IS 555. So no one will get a spammer call.HOWEVER, this means that this caller is somehow displaying (416) 555-7777 as his/her caller ID while calling from a different number.Furthermore, I saw the 647 number posted above. 647 is the Greater Toronto cell phone area code. So that may be a legitimate number. However, it may not necessarily be the number of the caller who was spamming you.I am dissapointed that some retard is giving a bad rap to the 416 :(

Called my mobile. Didn't answer as I was at work. I don't know anyone in Canada.

I received 2 calls from this number, one after the other.  It was an Indian man.  He was offering duct cleaning for $100.00.  When I said I wasn't interested, he insisted I should take his offer.  I told him I was on the "Do not call list" and he should know about that, and he didn't care.  He wanted me to take his offer.  I put down the phone.

This number has called multiple times the last couple of days.  Mostly shows up as 'unknown name', but did come up one time as 'sialk.ca' who appear to be a long distance reseller.

I finally did answer a call since the constant callbacks were annoying.  A woman asked for me by name and told me that Yak Communications asked her to call to give me a special money saving offer.  I cut her off indicating that the phone muber is on the National Do Not Call List, and asked they not call anymore.  Hopefully they will stop calling.

The calling card logic doesn't make any sense. Unless you live in Greater Toronto, why would you have a calling card where you will have to pay long distance? I have one to call family in the States but I use a 1800 one so THEY don't have to pay long distance.Suprisingly enough, I have never been called by these idiots, and I actually have a 416 number... Thank God for that though, that I've never been called.
