Try nomorobo. They get you to set up simultaneous-ring with one of their numbers. For each incoming call, if it fails their reputation scoring, their system simply "picks up" immediately and plays a pre-recorded message. Your main number then doesn't receive the call (timing issues notwithstanding).
They have an interesting way of building the reputation database: in addition to receiving customer reports, they buy Twilio's "dirtiest" phone numbers, the ones getting so spammed they're unusable by other businesses. If you call ~3 dirty numbers, welcome to the dynamic block list.
- tptacek 11y agoHow am I just learning about this now? This is amazing. You've been to my house several times; how did you never tell me "uh you know you don't need to be getting those robocalls you get all day"?

- TazeTSchnitzel 11y agoHere in the UK, calling your own number seems to be used exclusively for configuration stuff (voicemail etc.). Is there any normal use for it in the states? If not, surely you should just blacklist your own number? (I'm aware that any time you say "you should just ..." it's never that simple)
- j-conn 11y agoVery cool. Can they somehow detect / prevent malicious actors impersonating legitimate phone numbers to get them blacklisted?
- patio11 11y agoYou get an audio capcha ("This phone is protected by NoMoRobo. Press $NUMBER to prove you aren't a robot. Press $NUMBER to prove you aren't a robot. ... Goodbye.") $NUMBER is two randomly generated digits. Presumably one can feedback loop that into the reputation score. Honestly, though, I don't think this is a terribly likely attack.
- dfc 11y agoWow, this is a free service. What is the business model? I have my suspicions but I am trying to remain positive.
