Or why isn't the law enforced? Why is the FCC and do-not-call.gov asleep on the job? Why are scammers even allowed to spoof caller IDs from local area-code numbers that don't even exist? (Thankfully, this makes them blissfully easy to spot. But I fear someday the fraudsters will get up to speed on that heuristic.) Don't get me wrong, I'm all for a technical measure like the one you suggest — it appears to be sorely needed. But I'm dismayed at how little the government and the carriers care. And for God's sake can we choose a more convincing scam than "the factory warranty on your vehicle is about to expire"? My car is over 20 years old. The warranty is gone.
