title: Start remote-video skype for business
body: <p>I have a wpf-application which initiates a video-call to another endpoint (using the client-sdk, with UI suppression). That works fine so far - except that the remote-endpoint has to manually and explicitly activate video, so that he shares video as well.
  If I use the official S4B-Client, the video starts automatically. How can I achieve the same behaviour? Or is this a known limitation?</p>
