Twilio Click To Call 'no-answer' status in JavaScript client

Question

Is there any way to know if an outgoing call was not answered using only the Twilio Click To Call JavaScript client?

Twilio.Device.disconnect(function (conn) {
    logAndDisplay('Call ended');
});

Checking conn.status() after a call was not answered is 'closed' (same as if a call was answered) so there is no way to figure out the difference.

Before the JavaScript disconnect callback is called the no-answer status can be retrieved on the server from DialCallStatus. In case that status is not available on the client, is there a way to send the server value and access it on the client?

Answer 1

In the end I could not find how to read a no-answer status on the client.

The (hacky) solution was to make an AJAX request to the server to get that status.
