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?

also received a call from this number

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.

My family live in another country and they use phone cards to call me. This is the number usually displayed when they call me!

Get several calls from these people asking if I want a cash advance.  They want your bank account and routing number.  Will believe anything you say! Have fun with them.

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.
