I made a Lua class for Corona SDK which handles Twilio HTTP requests. With it you can build a cross platform app for managing your Twilio account, sending messages, making calls, or any of GET/POST request that twilio rest api can handle.Unfortunately you cannot do actual VoIP with my code. For that you’d have to create a native Android or iOS app. I was disappointed about this. My original intention was to make a voice visualizer in which voice would be sent to the app and turn into some kind of generative art. But that because I just read Generative Art by Matt Pearson and love that stuff. Completely useless, I know :D. Anyway, Twilio ought to hire me now, right?
