I am on the do not call list and I keep getting a call from the number.  It is on my cell phone which is a private number and I do not give it out to anyone so I have no idea how they got my number.  When I answer it there is no one there.

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.

Today I received a call from this number and could not hear anything, just somebody trying to say something but very far and very unclear. So, I googled the number and found all these comments here. In the meantime the phone rang again and it was my mom in law calling from abroad. I know that she is using a phone card to call abroad. So, this number is probably the number of the phone company that sells these phone cards. So people using these cards could be from anywhere in the world I imagine. Some just  misdial the number and get to you instead of the intended person and some might misuse the card to place a scam call. Just be aware it is somebody from abroad and might not necessarily be a bad person.

automatated phone call saying my debit card had had a security bleak and I needed to file a complaint immediately with them.  It then asked for my 16 digit debit card number.  I put in all 0's but it wouldn't let me any further.  I decided to hang up at that point and look it up on the computer.

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.

this number belongs to one of Bell's outsources centers for Bell Mobility. I've asked not just this center but also called in to Bell and added myself to the Do Not Call list several times and yet I continue to receive calls from Bell. Since is responsible for the administration and updating and registering the DNC List the least they can do is comply by it themselves. If not then they should not reserve the right to maintain the DNC List
