Steps to reproduce:

The JSEP 02 spec 7.1 shows this:

This example demonstrates a ROAP call, without the use of trickle
   candidates.

   // Call is initiated toward Answerer
   OffererJS->OffererUA:   pc = new PeerConnection();
   OffererJS->OffererUA:   pc.addStream(localStream, null);
   OffererJS->OffererUA:   pc.startIce();
   OffererUA->OffererJS:   iceCallback(candidate, false);
   OffererJS->OffererUA:   offer = pc.createOffer(null);
   OffererJS->OffererUA:   pc.setLocalDescription(SDP_OFFER, offer.toSdp());
   OffererJS->AnswererJS:  {"type":"OFFER", "sdp":"<offer>"}

   // OFFER arrives at Answerer
   AnswererJS->AnswererUA: pc = new PeerConnection();
   AnswererJS->AnswererUA: pc.setRemoteDescription(SDP_OFFER, msg.sdp);
   AnswererUA->AnswererJS: onaddstream(remoteStream);
   AnswererJS->AnswererUA: pc.startIce();
   AnswererUA->OffererUA:  iceCallback(candidate, false);

   // Answerer accepts call
   AnswererJS->AnswererUA: peer.addStream(localStream, null);
   AnswererJS->AnswererUA: answer = peer.createAnswer(msg.offer, null);
   AnswererJS->AnswererUA: peer.setLocalDescription(SDP_ANSWER, answer);
   AnswererJS->OffererJS:  {"type":"ANSWER","sdp":"<answer>"}

   // ANSWER arrives at Offerer
   OffererJS->OffererUA:   peer.setRemoteDescription(ANSWER, answer);
   OffererUA->OffererJS:   onaddstream(remoteStream);

   // ICE Completes (at Answerer)
   AnswererUA->AnswererJS: onopen();
   AnswererUA->OffererUA:  Media

We should implement the methods in the signaling code to support this feature.
