Surely the entire point of monitoring your calls is NOT to have to call back or interact with these annoying numbers.
Weak advice miked, you should be ashamed

repeated calls from this number. hangs up when we answer

I got this same . It called me twice today but i didnt pick it up

I am sick to death of calls from this number   Have just discovered it is TV Ontario.  They should identify themselves.  It is a cause worth supporting, which I do, but have now asked them not to call me.  Their telemarketing strategy needs to be improved.

I'm a musician and was doing a recording session in my home studio.  I was in the middle of a REALLY good take involving vocals when the phone rang, spoiling the take, and it was this number--showing up on the phone display not only as the number that was being called from, but also in the "caller name" field.  If it's truly TVO who called, they ought to be ashamed of themselves, since they of all people should know better than to disrupt an audio (let alone video!) production session.  Granted, they couldn't have *known* I was in the middle of a recording session, but couldn't they have anticipated that I *might* be?
