If I were able, I would disable incoming telephone calls entirely (consider that a feature request, Apple). The phone system today is fundamentally untrustworthy because of caller ID spoofing, and the phone companies involved are culpable for not addressing this problem.
A new ID system using PKI could eliminate the spoofing problem completely. Yes, I'm sure it would require a huge coordinated effort. Given spam calls will exceed 50% of all calls next year [1], this should be seen as an existential crisis for phone companies.

- mmirate 8y agoPublic-key identity verification wouldn't even require substantial upgrades to anything except the phone hardware itself - when making the call, just convey the signature upon connection via a dialup-modem-like encoding, and the receiver may at their discretion neglect to connect their audio hardware to the line until after verifying that data. (Could even use some kind of PoW as another option, for calls where the receiver is unlikely to have received your public key yet.)
