@lauren There's a big gap in my understanding of how scam callers stay on the network.
My uncle gets about three a day. All probably from the same company, because the prefix audio (the sounds their robocall machine makes patching through to a human being) are all the same. They call from dozens of different numbers.
Where has the phone network broken down that carriers can't just say "These numbers? They're scammers. Cut 'em?"
@mark @lauren They're not on the network. Thet buy spoofable VoIP accounts that provide virtually free (often billed at less than 1¢/min with 1-second-granularity billing) connection to call real phones & move providers constantly to avoid getting caught. Until that's taxed out of existence, spam calls are unfixable.
@robryk @dalias @mark CNID can be tampered with at any point along the line.
