I rarely receive calls these days and when I receive, they are mostly scams or telemarketers, so I basically accept call from a small set of whitelist and drop the rest. Most people who need to speak to me attempt to contact me via different means anyways. I don't have much faith they will ever fix PSTN that I'm dreaming for the day I can start ignoring all calls.
