Most robocalls are illegal in the US. We have a do not call list and everything. I believe is it a name change is currently working its way through to change the name to "seriously, do not call... please list". [https://www.forthepeople.com/class-action-lawyers/robocallin...]

The problem is that determining the source is difficult and even if you did it is most likely over seas where enforcing the fine is impossible.

I would love to hear a technical solution that has been implemented somewhere that had a significant impact.

There is a simple economic solution. Make the caller instead of the receiver pay for all calls.

This doesn’t work either. In india, calls are exclusively paid for by the caller but the number of unsolicited calls (and texts) is high.

The bigger problem is if they're scammers they wont care about a do not call list.
