It would be easier to pass a law preventing 'spoofing' of caller ID, which
telecom companies could easily enforce, and that would go a long way towards
enforcing the 'do not call' list.
Your suggestion of a private filter already exists. I have Xfinity home
phone service, and Comcast offers a service called Nomorobo
[www.nomorobo.com] that automatically screens all incoming calls and
compares them to a continuously updated list of robocall numbers. 99% of
the time my home phone will ring once, then stop.

Almost the opposite of the net neutrality problem:
To prevent spam phone calls, the phone companies themselves can't do much. Companies are not allowed to filter out calls. (The government could start throwing perpetrators in prison, and maybe they'd eventually get their come to Jesus moment.) It should be feasible enough, though, to market filters that only allow through the phone numbers a household wants to accept. A "white list," in short. Hey, it's better than just shutting off the ringer altogether.
