I may have written this in the past, but I still don't get why we still use PSTN where identifying caller is next to impossible, and very easy to be exploited (allowing mass dialing easily)
E-mail is not perfect, for example, but at least its address provides bit more context than the seemingly random number showing up, legit or not.
If we are insisting to use the current system, norm really should shift to a strict white list at least for residential inbound. The current system is simply not sustainable, and more and more people are not taking the call from the number they don't recognize anyways.
- tenebrisalietum 5y ago- PSTN is well-established. The phone network has had global reach for a very long time, probably longer than the Internet. Phone numbers have been part of people's lives for a century. - Some locations in some countries are probably still using mostly analog switching equipment and can't upgrade to cellular or anything more modern/secure for various reasons. - PSTN has government-agency or at least a subsidized/privileged monopoly status in most countries, so it won't die a natural death. I just wonder why it took until iOS 12 or whatever for my phone to be able to drop calls from unknown contacts.
