Your number is dialed by a computer at The Canadian Diabetes Foundation offices in Sudbury. The operator hears a beep and is supposed to assume there's a person there and start talking. If they don't hear the beep they don't start their appeal.  If your phone rings three times the auto-dialer figures you aren't there and moves to the next number. If you pick up the phone then, you get a dead line. (most likely it was your own breathing through the phone mic)  When the equipment realizes there is no connection it releases your line (click!)  At least with THIS number there isn't anything nefarious or nasty. I believe they are looking for used clothing donations.

Continuously receiving calls.
