There's no reason the phone system can't be fixed incrementally. They did it for 911 and location data, they can do it for ANI. After all, it's not like the phones themselves are faulty (well, maybe on the wireless spectrum, but that's a separate issue) If you want a solution, whitelisting isn't it. You could even create them at the organizational level, like schools and government offices publishing lists of numbers to be whitelisted... But that would just be used by the robocallers, spoofers and scammers. We as a society benefit hugely from instant communication and trying to remove it today would put too many people at risk.
