They just haven't figured out the best way to sell it as a feature to the end-user.

International telephone calls work because of interconnecting treaties and agreements in place between countries. There are a few bad actor foreign telephone companies out there, but it mostly works. Back when the 1-800 spoof scam (you call a 1-800 number which forwards you to a 1-900 number in a different country) was popular, I got a pretty good education on why telephone companies couldn't spot the scam and refuse to pay the foreign telephone company. The basic answer is legally they can't.
As far as interactive fraud detection goes, that stuff is mostly after the fact. The sheer volume of calls makes real time detection much more difficult than you think. Heck, real time call rating (which is what makes pre-paid mobile telephone possible) is both expensive and hard. It took years of work and many millions of dollars to get it to working in a timely manner at the company where I worked. Yea, it's possible to put in an anti-call-spoofer system in place, but it's both expensive and runs into legal issues.
