Twilio Redirect From Webhook

Question

I've been trying to redirect incoming phone calls from Twilio via webhook to execute TwiML hosted on a website.

For testing, I've been using 'raw' GitHub to host my XML as a 'GET' request webhook.

My code is in the format below:

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Dial>
        <Number>
            +447xxxxxxxxx
        </Number>
    </Dial>
</Response>

When I run this code from a TwiML bin, it redirects as I want, however when I send it through a webhook, it just says the phone number out loud.

Any help on why this is would be greatly appreciated,

Thank you.

This has to do with the MIME type the web server is returning.

You can find more details here.

The webserver is returning text/plain instead of text/xml.

You can host your static TwiML in a TwiMl Bin.
