Eliminating Robocalls

Roll ahead to 2019: if you have the right access, hardware and/or software — you can initiate a call on the network, from any phone number, to any phone number in a (pretty much) untraceable way. All of this is on top of our Terms of Service and Acceptable Use Policy, which expressly prohibits “using the Twilio Services in connection with unsolicited, unwanted or harassing communications (commercial or otherwise), including, but not limited to, phone calls, SMS or MMS messages, chat, voice mail, video or faxes.” Some very smart people have been working on new ways of cryptographically signing calls – a digital signature – proving ownership of a phone number before the call is initiated.
