I have been getting calls from this number. How do we block it??

been getting calls from telemarketers, this guy being the main offender.

Received a call from them here in Saskatchewan this morning. Still scamming, I see. This time though it started as a recording. "Due to the..." (click - I hung up)

I received a HANG UP call from this number.  That only makes me NOT want to donate to their "charity".  Are they a legitimate charity?  I checked out the web site.  Very little info on the site.  I emailed them and said such calls are a total turn off.  Is it offshore telemarketers who have no manners?  Are they american telemarketers who are just plain rude?  the number on call display means nothing.  I have received other hang up calls and when i call back I get "this number is not in service".  How can that be?  the scammers are obviously smarter with technology than I am.  Or maybe i an just too honest and polite.

I received a call today, and the rude insistant man on the line said he was raising funds for Lukemia research.  After listening to his speal, and telling him I don't give information on the phone, but said if he mailed it to me I'd look, he tried to tell me I he wasn't getting through to me.Anyway, with his attitude, and the google history of this number, I believe that it is a scam number being used.  I would advise not to give money to this phone number.
