title: How to allow auto connect to microphone through web application on chrome without messages
body: <p>I have recently been developing twilio web application. My application can receive calls. This feature is OK. But When answer button is clicked, message pops up "localhost want to use microphone". I want to avoid this message. I want to answer call once when answer button is clicked without any messages. Is it possible? if possible how can I do it?</p>
