title: Is it possible to detect WebRTC one-to-one audio or video call duration in Node?
body: <p>I am very new to webrtc, I am slightly confused about it.</p>
  
  <p>I am able to do one-to-one video/audio call using node.js, but still confused is it possible to check how long two people had talked?</p>
  
  <p>If yes, please guide me.</p>
  
  <p>If not then what is the best way to monitor call length? (I don't want to record audio or video, just the length).</p>
  
  <p>Thanks in Advance.</p>
