title: How to clear RTCPeerConnection (WebRTC)?
body: <p>Has anyone seen that error, literally:</p>
  
  <p>"<strong>Uncaught DOMException: Failed to construct 'RTCPeerConnection': Cannot create so many PeerConnections</strong>"?</p>
  
  <p>I guess it's happens because I didn't removed connections (maybe not, maybe it's because I didn't provide more memory or something). But from where? Where do they accumulate?</p>
  
  <p>I didn't found answer for the question, literally, nowhere.</p>
  
  <p>I was tried to solve that problem a couple days. By the way, no such thing as a stupid question, right?</p>
  
  <p>UPD: Forgot to add that I using sip.js library.</p>
