Can you extend a bit on that, maybe I'm not understanding the problem right. Isn't having calls being authenticated the first step before you have whitelist/blacklist? Once every call can be definitively attached to a given source, then you can ban any foreign provider that let's these proliferate completely, no?
- davidajackson 7y agoSHAKEN/STIR + Whitelisting is the best solution. SHAKEN/STIR by itself isn't going to change things too much I think. But it is a step in the right direction. Whitelisting without SHAKEN/STIR is still extremely functional. There are billions of unique American numbers possible, and with 250-500 average contacts per random dial, contact spoofing is not statistically significant.

- davidajackson 7y agoGood point, if they're calling from a specific number. I see of lot of complaints about companies like FedEx though, where the calls come from random numbers.
- ehsankia 7y agoThat's what I was getting at, S/S seems like a foundational step, before being able to whitelist/blacklist. You first need to be certain about the source of the call before you can actually moderate it. Without authentication, spoofing makes banning numbers meaningless and dangerous.
