This PHP-Laravel sample application is a Rapid Response Kit built by Twilio for organizations that need to act quickly in disastrous situations. It allows aid workers to communicate immediately with volunteers, spin up conference lines, and broadcast spoken messages to phone numbers. The app uses Twilio's REST API and PHP library to generate TwiML responses, which are then sent back to Twilio's servers. The application includes features such as moderating conferences, recording and playing back messages, and broadcasting messages to phone numbers. It also includes a webform for organizing volunteers and selecting roles. The app uses Laravel's routing system and Twilio's PHP library to handle incoming calls and requests.
