Hi there,
Hope you are doing well. I have read and understood your requirement partially. But I have worked on many webrtc projects. I have very good experience on WebRTC for web, android and iOS, Openvidu, COTURN server and Kurento Media server. So, if you give me a chance to understand your requirement by giving me some more info, then I can definitely complete your project with minimum cost and time. Waiting forward to your reply...
