AIUI spoofing is possible because the phone systems were designed back in the days when a single entity controlled the entire network and so everything just trusts everything else. That said, I don't know why we still haven't fixed this. We've had plenty of time. I guess the answer just comes down to it costs money to fix it and the phone companies historically haven't cared. Though at this point, given how many people outright refuse to answer numbers they don't recognize due to spammers, you'd think the phone companies would be feeling financial pressure to work towards restoring trust in the phone system.

But by not fixing the issue now it will also destroy all future business. So short-sightedness.

What financial pressure do the phone companies feel when I never answer my phone? I still have to give them identical amounts of money to maintain my internet connection.
