It sounds like it shouldn't even be happening in USA. It's a trivial bit of code in the routing software to check if CLI matches SS7. If it doesn't: don't connect. You don't even need to correct it. There's no legitimate reason to connect a spoofed number.

Spoofing is a service that the telcoms offer. Not a weakness! At least, that's how they see it.
