Doc Edward Morbius ⭕How would you suggest fighting robocalls and phone spam?
Friends in the US are reporting that over 45 of the past 50 calls they've received are robocalls, telemarketers, hang-ups, misleadingly-identified, or otherwise smell strongly of fraud.
STIR/SHAKEN was rolled out two years ago and has quite obviously failed. See: https://www.theverge.com/2021/6/30/22557539/t-mobile-verizon-carriers-fcc-stir-shaken-certification-deadline-spam-calls
I'm looking for systemic solutions here, not personal mitigations. "I've stopped using the phone and am now only communicating by Ansible" may suit you very well, but it doesn't address the billions of people who do have directly-addressable voice coms as mobile or landline service.
Examples of systemic solutions:
Think regulation, making global changes to software or hardware, changing switching and call handling systems, or market-based interventions, such as:
- Bonding callers and telcos. Spam calls would generate compensation from the telco to the subscriber. Telcos would bond for network interconnects, failure to maintain low-spam-call SLAs would forfeit bond.
- Direct reporting from all phone systems (mobile, VOIP, or landline) of spam calls.
- Expanded phone numbers. A sparsely-populated address space would make random war-dialing less viable, individuals might provide distinct numbers to each individual contact. (Organisations couldn't fully rely on this but might in part.)
Things of that nature.
NOT "I downloaded this app and use it on my pocket spy device."
Boosts very much welcomed.
