. Here are the steps on how to integrate STUN and TURN servers specifically using the Coturn Docker image into your Node.js Kurento.js video chat app: Install Docker on your remote machine. You can follow the instructions here: https://docs.docker.com/engine/install/ubuntu/ Pull the Coturn Docker image. You can do this by running the following command: docker pull coturn/turnserver 3. Create a new Dockerfile on your remote machine. The Dockerfile should contain the following lines: FROM coturn/turnserver # Set the TURN server's public IP address ENV TURN_SERVER_PUBLIC_IP= # Set the TURN server's username and password ENV TURN_SERVER_USERNAME= ENV TURN_SERVER_PASSWORD= # Start the TURN server CMD turnserver -u -p -a 4. Build the Docker image. You can do this by running the following command: docker build -t turnserver . 5. Run the Docker image. You can do this by running the following command: docker run -d -p 3478:3478 turnserver 6. Configure your Node.js Kurento.js video chat app to use the TURN server. You can do this by adding the following lines to your app's configuration file: turnServers: [ { url: turn: :3478 username:   password:   } ] 7. Test your app. You can test your app by running it and then trying to make a video call with another user. If everything is configured correctly you should be able to see each other's video. Here are some additional tips for configuring and testing your setup: Make sure that the TURN server is running on a public IP address. If the TURN server is running on a private IP address you will not be able to connect to it from outside of your network. Make sure that the TURN server is using the correct username and password. If you specify the wrong username or password you will not be able to connect to the TURN server. Test your app with multiple users. If you can only make a video call with one user it is possible that there is a problem with your TURN server configuration. I hope this helps!
