Twilio call autodisconnect

Question

I am making browser to browser call, after successfully call establishment, the call disconnects automatically. The receiver isn't getting incoming function executed. Can anyone help me out?

Twilio.Device.setup(token, { debug : true});

Twilio.Device.ready(function (device) {
    console.log("Client '' is ready");
    //! Ready
});

Twilio.Device.error(function (error) {
    console.log("Error: " + error.message);

});

Twilio.Device.connect(function (conn) {
    console.log("Successfully established call");
});

Twilio.Device.disconnect(function (conn) {  
    console.log("From:" + conn.parameters.From);
    console.log("To:" + conn.parameters.To);
    console.log("Call ended");

});

Twilio.Device.incoming(function (conn) {
    console.log("Incoming connection from " + conn.parameters.From);
        // accept the incoming connection and start two-way audio

        conn.accept();

});

function call(id) {
    console.log('calling started! to ' + id);
    callto = id;
    params = {"client": id};
    Twilio.Device.connect(params);

}

I am using socket to connect the callers! When a second user comes into scene, the call is made to the receiver by the sender. The incoming function is not working in receiver side.

Fixed! As the site was secure, made a new TwiML application with new request url to receive and make calls via the browser. Thanks to @philnash for helping me sort out the issue
