Please please help in setting up Turn server in Ubuntu, such that we can have video call even connecting from different network.
I have installed using below command in Ubuntu 20.10 : sudo apt-get install Coturn.
Can any one suggest how I should configure turn server to achieve above mentioned issue.
You should start looking at the example configuration.
Adapt it your your needs (host public IP address and realm), then restart coturn.
Then you can test it with tools like test.webrtc and WebRTC sample for Trickle ICE (or your own client application).
