This application uses Twilio's Voice and SMS services to accept incoming text messages and record voicemail messages. The recorded audio is then saved to a MongoDB database, along with other metadata such as the caller's phone number, location, and message content. The application also includes an admin interface for moderating and displaying messages, as well as an AngularJS-powered front end for user interaction. Additionally, Rev.com's transcription APIs can be used to provide accurate human-powered transcriptions of voicemail messages. The application is built using node.js, Express, mongoose, Less CSS, browserify, AngularJS, Buzz, Heroku, and MongoHQ.
