Here's a suggestion for reducing scam calls. If I was able to restrict my incoming calls to a list of 1-10 Canadian area codes provided by me this would eliminate virtually all my unwanted calls. If this was feasible, the idea could be extended to allow me to add perhaps 1-10 additional phone numbers that would be accepted (eg. Uncle Charlie in Washington, DC).
Scamming is causing serious damage particularly to senior citizens and our police services are having great difficulty in tracking down the scammers. Hopefully the industry can provide customers with some options that may help reduce or eliminate this problem.
