We just received a call from this number....dead air then sounded like a boilerroom & he said hello, I hung up! Area code & exchange are classic Cambridge ON.

We just received a call from (519) 624-6548 as well.  They did not leave a message with the answer machine picked up.

It's a guy talking about duct cleaning who hung up as soon as I tried to tell him to take my name off his calling list.  Called the # and it was some company that didn't do duct cleaning. Their phone line has been hacked.
