I've been wanting something like this to be done for years - the telcos could have dealt with this on their own but need to be forced to do it by the feds.
I have a petition opened with the Canadian Federal Government to regulate all calls that show a phone number must be matched to the origin. This is intended to block scammers from faking a display number. This should end most scam calls. www.ourcommons.ca/petitions/en...
