Overview

• Runs in the browser and Node.js.
• SIP over WebSocket (use real SIP in your web apps)
• Audio/video calls (WebRTC) and instant messaging
• Lightweight!
• Easy to use and powerful user API
• Works with OverSIP, Kamailio, Asterisk. Mobicents and repro (reSIProcate) servers (more info)
• Written by the authors of RFC 7118 "The WebSocket Protocol as a Transport for SIP" and OverSIP

Getting Started

The following simple JavaScript code creates a JsSIP User Agent instance and makes a SIP call:

// Create our JsSIP instance and run it:

var configuration = {
  'ws_servers': 'ws://sip-ws.example.com',
  'uri': 'sip:[email protected]',
  'password': 'superpassword'
};

var ua = new JsSIP.UA(configuration);

ua.start();


// Make an audio/video call:
var session = null;

// HTML5 <video> elements in which local and remote video will be shown
var selfView =   document.getElementById('my-video');
var remoteView =  document.getElementById('peer-video');

// Register callbacks to desired call events
var eventHandlers = {
  'progress': function(e){
    console.log('call is in progress');
  },
  'failed': function(e){
    console.log('call failed with cause: '+ e.data.cause);
  },
  'ended': function(e){
    console.log('call ended with cause: '+ e.data.cause);
  },
  'confirmed': function(e){
    var local_stream = session.connection.getLocalStreams()[0];

    console.log('call confirmed');

    // Attach local stream to selfView
    selfView = JsSIP.rtcninja.attachMediaStream(selfView, local_stream);
  },
  'addstream': function(e){
    var stream = e.stream;

    console.log('remote stream added');

    // Attach remote stream to remoteView
    remoteView = JsSIP.rtcninja.attachMediaStream(remoteView, stream);
  }
};

var options = {
  'eventHandlers': eventHandlers,
  'mediaConstraints': {'audio': true, 'video': true}
};


session = ua.call('sip:[email protected]', options);
