I got fed up waiting for this years ago. Its quite simple to install/employ a system that allows the phone to ring only on numbers designated by the user. In my case if I don't have your number saved the phone is ALWAYS silent. It is so nice to settle in for the evening and literally never get a sales call to interrupt my family time. The Gov allows far too many exceptions to the no call list. Political, charity, etc... ------ they still call because they get a pass. Hmmm, the politicians get a legal pass, does that surprise anyone? In the USA it is election time and it would be interesting to know how many calls I won't get from Aug ---- > Nov. Who cares??
The biggest problem is Caller ID spoofing. There should no way for anyone to do that in the first place. I use a call blocker myself. No way around it these days. I wish them luck on stopping this huge nuisance.
I fully understand how Caller ID spoofing works. I have never been a victim of it however, that I know of. Usually its a spoof of someone trying to look like police, or a recognized charity and mostly preying upon older folks that feel they "HAVE TO" answer the phone. My father-in-law acts like he would die if he had to let a phone go unanswered, even if he sees "unavailable" on his caller ID. I can't envision a solicitor spoofing that they are one of my friends, so in my case even spoofing would be of no value to the calling organization. They can leave a message, but they never do of course.
