Make it illegal for calls originating from international origins to lack caller identification. Also likely unenforceable, but again, it sets the basis.

Since I sense that caller ID is completely spoofable for calls from international networks, now add some technical salt: Require domestic phone companies at the edges to add some kind of "network of origin" prefix to caller IDs from international origins. This is prepended to what is provided by the outside network, even if they provided "no caller ID" or "unknown caller".

Make it that domestic calls don't have this prefix and it is illegal to insert anything that resembles one.

This way I can see incoming calls from network Xyzabc for the junk they are. And networks will each get a reputation from consumers.

I can dream.
