title: Does ORTC and/or Edge support DataChannel?
body: <p>Finding definitive information on ORTC seems difficult, and finding examples even more so.  I need to send strings between iframes and was looking into using WebRTC but in order to support Windows Edge I have been looking into ORTC.  I wanted to see if anyone had successfully used some sort of data channel with ORTC in Windows Edge.  I thought ORTC was specifically for Edge but it seems to define a data channel but Edge does not implement it.</p>
  
  <p>The information I have come across leads me to believe that ORTC cannot do data channels, despite the fact it is listed in their API.</p>
  
  <p>RTCDataChannel defined in the API, section 11.3 <a href="http://publications.ortc.org/2016/20161202/" rel="nofollow noreferrer">http://publications.ortc.org/2016/20161202/</a>)</p>
  
  <blockquote>
    <p>The RTCDataChannel interface represents a bi-directional data channel between two peers. </p>
  </blockquote>
  
  <p>But at <a href="https://docs.microsoft.com/en-us/microsoft-edge/dev-guide/realtime-communication/object-rtc-api" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/microsoft-edge/dev-guide/realtime-communication/object-rtc-api</a> I found:</p>
  
  <blockquote>
    <p>Since Microsoft Edge does not implement the data channel, the RTCDataChannel and RTCSctpTransport objects are not supported.</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>Microsoft Edge currently does not support any of the DataChannel functionality currently defined in the ORTC spec.</p>
  </blockquote>
  
  <p>Please offer additional resources I can research in order to have a definitive answer.  Also helpful would be any resources stating whether Windows Edge will in the future be supporting this.</p>
