The Twilio.js library allows developers to establish audio connections between a web browser and a Twilio Application. Including the Twilio.js library gives developers access to a couple of objects. One, Twilio.Device, allows one to make outbound connections, accept incoming connections, and set up connection event handlers. Another object, Twilio.Connection, allows an application to interact with a call as it is happening -- mute, unmute, or send DTMF tones. The extensive documentation includes a Quick Start option.
Today there were two major announcements from Twilio (a ProgrammableWeb sponsor) as its Twilio API continues to expand into Europe. Twitter also announced an upcoming change that will free the retweet count for a tweet into the API results. That and seven new APIs round out today in APIs.
