WORLD'S FIRST HTML5 SIP CLIENT

This is the world's first open source (BSD license) HTML5 SIP client entirely
written in javascript for integration in social networks (FaceBook, Twitter,
Google+), online games, e-commerce websites, email signatures... No extension,
plugin or gateway is needed. The media stack rely on WebRTC.
The client can be used to connect to any SIP or IMS network from your preferred
browser to make and receive audio/video calls and instant messages.

JAVASCRIPT SIP/SDP STACK

The SIP and SDP stacks (~1 Mo) are entirely written in javascript and the
network transport uses WebSockets as per rfc7118. The live demo doesn't require
any installation and can be used to connect to any SIP server using UDP, TCP or
TLS transports.

Short but not exhaustive list of supported features:

 * Works on Chrome, Firefox, IE, Safari, Opera and Bowser
 * Audio / Video call
 * Screen/Desktop sharing from Chrome to any SIP client
 * Instant messaging
 * Presence
 * Call Hold / Resume
 * Explicit Call transfer
 * Multi-line and multi-account
 * Dual-tone multi-frequency signaling (DTMF) using SIP INFO
 * Click-to-Call
 * SIP TelePresence (Video Group chat)
 * 3GPP IMS standards

MEDIA STACK

The media stack depends on WebRTC (Web Real Time Communication) which is
natively provided by the web browser. sipML5 should work on any web browser
supporting WebRTC but we highly recommend using Google Chrome or Firefox Nightly
for testing.
For Safari, Firefox, Opera and IE you will need to install webrtc-everywhere
extension.



INTEROPERABILITY

Using sipml5 and webrtc2sip.org you can call any SIP-legacy endpoint or PSTN
network.

PROGRAMING WITH SIPML5 API

The API is designed with love to make it easy to develop rich and robust HTML5
applications in few lines of code.
No need to know how SIP work to start writing your code. Using this API, it will
be a piece of cake to write HTML5 VoIP applications.
Below, a very compact code showing how to initialize the engine, start the stack
and make video call from bob to alice in less than 15 lines:


                        SIPml.init(
                                function(e){
                                    var stack =  new SIPml.Stack({realm: 'example.org', impi: 'bob', impu: 'sip:bob@example.org', password: 'mysecret',
                                        events_listener: { events: 'started', listener: function(e){
                                                    var callSession = stack.newSession('call-audiovideo', {
                                                            video_local: document.getElementById('video-local'), // <video id="video-local" .../>
                                                            video_remote: document.getElementById('video-remote'), // <video id="video-remote" .../>
                                                            audio_remote: document.getElementById('audio-remote') // <audio id="audio-remote" .../>
                                                        });
                                                    callSession.call('alice');
                                                } 
                                            }
                                    });
                                    stack.start();
                                }
                        );
