A Javascript SIP client based on SIP.js.

ctxSip is a Javascript based SIP client that uses WebRTC and WebSockets to connect to your SIP server. The UI is designed to be launched as a popup from within your application. Works well with Kazoo from 2600hz

• Audio only, Hold / Resume, Mute, multiple call support.
• No plugins required, Works with WebSocket / WebRTC enabled browsers. (Firefox & Chrome, for now Safari 8 when it is released.)
• Call log is saved to localStorage.
• Intuitive interface makes it easy for users.
• Easy to configure and integrate into your project.
• MIT licensed.

You will need a sip account on a server that supports SIP over websockets. This has been tested with Kamailio in front of Freeswitch.

• Clone this project.
• Copy phone/scripts/config-sample.js to phone/scripts/config.js
• Edit phone/scripts/config.js to reflect your sip account.
• In your application HMTL, create a document and add the following code:

<a href="phone" id="launchPhone">Launch</a>

<script>
var url      = '/phone',
    features = 'menubar=no,location=no,resizable=no,scrollbars=no,status=no,addressbar=no,width=320,height=480';

    $('#launchPhone').on('click', function(event) {
        event.preventDefault();
        // This is set when the phone is open and removed on close
        if (!localStorage.getItem('ctxPhone')) {
            window.open(url, 'ctxPhone', features);
            return false;
        } else {
            window.alert('Phone already open.');
        }
    });
</script>

SSL connections work best because they will allow the user to save the media preferences.
