I still don't understand how hard it would be for major phone carriers to validate the source and let the calls thru. Wouldn't it be possible just to allow Verizon to TMobile, or ATT to Verizon, since they both have their user info and can validate each other's calls? I mean, I can see their names on my phone, why not just add a little bit more info to make it more legit.

What about the non-major providers? They are no longer allowed to operate?

This is happening, but slowly. It is a huge problem to get all carriers / phone operators to get this installed enough to be useful.

Research SHAKEN/STIR to see more about it.

Here's an example between AT&T and Comcast: https://about.att.com/story/2019/anti_robocall.html
