Fork Stream

Studio uses Widgets to represent various parts of Twilio's API that can then be stitched together in your Studio Flow to build out robust applications that require no coding on your part.

The Fork Stream Widget allows you to send real-time audio streams of a phone call over the Internet. Websocket and SIPREC protocols are supported.
