Telnyx WebRTC SIP JavaScript library

The Telnyx SIP-based WebRTC JS library powers up your web application with the ability to make and receive phone calls directly in the browser.

Check out the library in action in this web dialer demo.

Looking for more WebRTC features, JSON-RPC support or need to quickly get spun up with a React app? Telnyx also has a robust WebRTC SDK available as a separate npm module.

Installation

Install this package with npm:

$ npm install --save @telnyx/rtc-sipjs

or using yarn:

$ yarn add @telnyx/rtc-sipjs

Import TelnyxDevice in the module where you need it.

import { TelnyxDevice } from '@telnyx/rtc-sipjs';
