title: How to cold transfer a call from Flex to an external phone number?
body: <p>Currently I'm using <a href="https://github.com/twilio-professional-services/flex-dialpad-addon-plugin" rel="nofollow noreferrer">this plugin</a> as a template for warm transferring a call to an external number, but would really prefer to be able to cold transfer. I tried invoking the <code>wrapupTask</code> action after adding the participant to the call, but the call would end for everyone.</p>
  <p>Another thing I noticed was when warm transferring to the external number, the caller Id is my Twilio number - is there a way where the caller Id can be the number of the person that called in?</p>
