Seems to be a persistent fax machine. I've received two calls from it just today. When I attempt to call the number I get a message telling me the number is not in service.

they call and don't leave message. knuckleheads. Likely a telemarketer or junk fax

I receive this number yesterday evening, and it's looking for my mom and she not home, they said they were calling from something mail, whatever, I don't remember. I ask them what do they want, but they didn't answer me, they said what is the good time to call back, I said don't know, then they hang up. Then later I was trying to call back, I heard a message saying that the number is not in service.

Got a call from 416-255-9375 and thought it might be legit as it wasn't one of the twenty 866 numbers that call everyday.

Answered, said "Hello" a few times. Nothing. Hung up.

got a call from (416) 255 - 9375 just after 5PM, looked like a real toronto number so i answered it, said hello a cupple times to no reply, so i hung up.
