One is welcome to ship an Asterisk implementation of it any time one feels like doing so.  One has not shipped an Asterisk implementation.  One may underestimate to which degree ideas, revolutionary or otherwise, are improved by actually shipping concrete instantiations of them which actually work.<p>Incidentally: NoMoRobo gains some utility specifically because Twilio exists.  A trivial example: phone numbers have a history to them.  Most customers of Twilio want to buy phone numbers with a relatively clean history, i.e., ones that were not widely distributed prior to their life with that customer, to avoid misdirected calls or e.g. reputational issues.  NoMoRobo wants precisely the opposite -- they literally ask Twilio to provision them with phone numbers which are otherwise unsaleable to customers, for example because those numbers are actively getting spammed to death.  (Twilio has an entire team of people whose job is telephone number quality.  Things you wouldn&#x27;t have guessed existed in the world, right?)<p>This works great for NoMoRobo&#x27;s use case, because a phone number getting spammed to death is perfect for them -- it lets them cheaply capture a lot of phone numbers which one has a high confidence are spam rather than ham.
