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.

I just received the call from (416) 555-7777 but I didn't answer and no one left a message. I will see if they call back, and, if so, give them a piece of my mind. Are they just scammers or what?

just got a call about 5 mins ago, it was an indian man asking about a car, and how i have his daughters number and to give her a call back. it was extremely broken english and almost too hilarious.

On my display, it showed sialk.ca

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 :(

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.
