I see people here saying that spoofed numbers is the problem. Maybe it's a big part of it, but at the end of the day, the phone companies are complicit with the criminals because there's no good reason that these robocalls can't be treated like a DoS attack.
These crooks make millions, of calls every year. My first employer was apparently making robocalls, though none of us were aware of it(there was a call center with actual human beings), and they were cracked down on by the FTC a few years ago.
The way I see it, there's no good technological reason why a system couldn't detect millions of calls coming from one place, compare that with the number of complaints and number-spoofs, and trigger an investigation. The dinosaur phone system needs to either go extinct or be reformed, and the telecom companies don't give a fuck. Every time I've asked either T-mobile or AT&T to block the relentless robocalls, they tell me to install some 3rd party Android app that fails to effectively block calls.
