iOS supports seamless call blocking via inexpensive 3rd party apps like Hiya. Hiya works great, calls that are suspect get labeled and calls that are verified fraud or marketing are never seen but available in call history. This been around since iOS 10 maybe longer.

This does not solve the fundamental issue, which is that it is trivial to spoof caller id. I get random numbers every day from scammers. We need a system where callers can certify who the callers are reliably.
