Twilio.js allows you to make voice calls to and from a web browser and a
Twilio TwiML Voice Application.
This means you can open inbound and outbound audio
connections to Twilio for building soft phones, walkie-talkies, conference
calls, click-to-talk systems, and more, all from the browser.
Twilio.js is currently available under the following releases:
- twilio.js 1.4. This is the currently Generally Available (GA) release. It receives regular improvements and bug fixes. This is the release to use for new projects, and the one to upgrade to from older versions.
- twilio.js 1.3. This release is in maintenance mode. Only security and critical bug fixes are backported to this release. Customers are encouraged to upgrade to the 1.4 release at their convenience. This release will begin its end-of-life process once a new, future minor release of twilio.js, e.g. 1.5, goes live (becomes Generally Available).
The following older releases of twilio.js are deprecated. Customers are strongly encouraged to upgrade to twilio.js 1.4. We have provided a detailed Migration Guide to assist with the upgrade:
