Record Bad Customer Service Calls in 30 Lines of Ruby

This article describes a Ruby-based solution to record phone calls made to a Twilio phone number and send the recording as an SMS to the caller's phone number. The code uses Sinatra, a lightweight web framework, and the Twilio Ruby gem to interact with Twilio's REST API. By setting up a local development machine with ngrok, a publicly accessible URL can be created for the recorded call. When a call is made to the Twilio number, it triggers a POST request to the `/call` route, which generates TwiML and starts recording the call. After the call is finished, the `after-record` callback is triggered, which sends an SMS with a link to the recorded call using Twilio's REST API. The code was built using only 30 lines of Ruby, making it a concise solution for consumer protection against bad customer service.
