Getting it right is hard.
You are technically correct, the best kind of correct. Seriously though, a bunch of the conversation about shaken/stir and various problems with spam callers reveals: "telcos don't care (for any reason you can imagine)" "gov't mandates aren't really going to help" "people care as recipients of these calls, but really there are options for them as well to not get the calls (or not answer them)" I like that Mr Thomas's answer: "Why can't we just cryptpgraphically sign the caller's ANI and use that as a method to ID real callers we care about?" since that was my suggestion to the stir folk in their very first meeting... "what about ebony phones!" said the lawyer from telco-ville.
