received calls from this number two nights in a row.  when you answer - they disconnect.  tried calling back - just rings and rings and finally there's a busy signal.
get a life already.  Morons.

same here 6 today, 4 yesterday and 2 before that , no message and if I answer they hang up, pervs!

This number jsut called me 5 minutes ago and said he was from some
window company and asked to speak with the owner of the house.
I said he was not home at the moment, I'm not a kid by the way, I would no
better haha.  Weird though!!

Same here.I'm with MTS; maybe they're doing testing of their land lines?

This GT Group is a subsidiary of Bell Canada. I called them and they said it sounds like a computer generated autodialer.They could not provide the information required to fix it but suggested it be reported to the Police as an abuse issue. There is a department which deals in this area and can request the private info on the calling company and make it stop.

same thing here , just called .. my brother called back and he said the exact same thing.

funny thing may be related or not i don't know but someone rattled the door knob on my door while i was taking care of business and bros were at work.  don't know wtf is happening these days.
