Getting Started

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 for are required for this to work!
