title: Having multiple peers PeerJS?
body: <p>Here is my code for connections with PeerJS:</p>
  
  <pre><code>var peer = new Peer({ key: '[PeerJSID]', debug: 3});
  peer.on('open', function(){
    $('#my-id').text(peer.id);
  });
  // Receiving a call
  peer.on('call', function(call){
    // Answer the call automatically (instead of prompting user) for demo purposes
    call.answer(window.localStream);
    step3(call);
  });
  peer.on('error', function(err){
    alert(err.message);
    // Return to step 2 if error occurs
    step2();
  });
  // Click handlers setup
  $(function(){
    $('#make-call').click(function(){
      // Initiate a call!
      var call = peer.call($('#callto-id').val(), window.localStream);
      step3(call);
    });
    $('#end-call').click(function(){
      window.existingCall.close();
      step2();
    });
    // Retry if getUserMedia fails
    $('#step1-retry').click(function(){
      $('#step1-error').hide();
      step1();
    });
    // Get things started
    step1();
  });
  function step1 () {
    // Get audio stream
    navigator.getUserMedia({audio: true, video: false}, function(stream){
      // Set your video displays
      $('#my-video').prop('src', URL.createObjectURL(stream));
      window.localStream = stream;
      step2();
    }, function(){ $('#step1-error').show(); });
  }
  function step2 () {
    $('#step1, #step3').hide();
    $('#step2').show();
  }
  function step3 (call) {
    // Wait for stream on the call, then set peer video display
    call.on('stream', function(stream){
      $('#their-video').prop('src', URL.createObjectURL(stream));
    });
    // UI stuff
    window.existingCall = call;
    $('#their-id').text(call.peer);
    call.on('close', step2);
    $('#step1, #step2').hide();
    $('#step3').show();
  }
  </code></pre>
  
  <p>I borrrowed this code, and I was wondering it is possible to have multiple connections between peers, like a call group. My hypothesis is that all I would have to do is add a new audio object when the peer detects that a new person is calling, and then have it so the different users receive the ids of the other users and have audio objects added to their pages as well. Would this work? Is there a more efficient way to do it?</p>
