Not sure how fundamental it is, e.g., is it fundamental to bar ad-hoc caller-ID functions and require displaying the actual number & name of the account (maybe allowing additional info also)? Telcos already pass on this info - how big a deal is it to transmit accurate data?

But even if it is fundamental, such fundamental change is needed.

Part of the problem I believe is a great many people (even the telcos) view voice calls as a dead technology on it’s last legs. Almost no one wants to invest in it, and even fewer technical people want to build a career on figuring these issues out.

If regulators and the industry saw a future in figuring this out (as compared to dealing with another hassle from a unsexy legacy technology mostly used by old folks), it would have been solved a long time ago.
