FCC slaps $300M fine on “largest illegal robocall operation” it’s ever seen

Can someone with more technological knowledge explain how this is still a problem in current year? How is number spoofing still a thing? These can't be hard problems to solve.

The phone carriers can detect a huge number of calls from the same source and perform some automated checks, hey it is the same size data packet every time, and get their internal team to sniff out the spammers. The reason why they don’t do this? I have no ideas.

Money. They know they can't monetize it, so they just don't do it.

Caller ID isn't authenticated. The old way is that PBX systems could set the Caller ID to give number for extension. The new way is that VoIP callers set whatever number they want.

The FCC is pushing STIR/SHAKEN protocols to add authentication. It is supposed to have been rolled out in US in 2021. I don't know if it solves the problem of overseas VoIP calls since it sounds like only authenticates between providers in US.
