Great idea! Telemarketers have ruined the phone network for me. I haven't answered an unknown call for the past 10 years, which sometimes means I miss important ones. 99.9% of all calls are an attempt to get money, and the 0.1% that's a dentist appointment, a friend that changed numbers or whatever become collateral damage. A ban is the right idea but I wonder how they can handle it, logistically. I think there needs…
I never understood what are the technical obstacles to building the phone network in such a way that caller numbers can not be spoofed or suppressed. Then, you could just build a system where receiving an unsolicited phone call from a commercial entity entitles you to a compensation in small claims court, to the tune of 50 EUR, unless the caller can prove that you explicitly authorised them.
The problem is that enforcement of breaking the regulation is so non-existent that the criminals just place millions of calls knowing, at most, they might get a minor slap on the wrist that can be budgeted for as a "cost of doing business".
Every single call carried across the phone network is billed, and every hop along the path knows who to bill for their part of carrying the call. The billing system is the method to trace back to the originators, and then apply a fine sufficiently large enough to no longer be a cost of doing business.
But the regulators seem to have no idea that the billing system provides the traceability to find the criminals and then go after them. Instead we get things like stir/shaken that are trying to patch "authenticity" on top of a network never designed with that in mind.
