Server

You need two servers, Signaling server and Turn/Stun Server

Signaling Server

Use this repository: flutter_webrtc_server

Turn Server

For turn server use this link: coturn server

Config

Config coturn server

By using the above link, config the coturn.

• if you want to use coturn and signaling server in the same machine, use this config in /etc/turnserver.conf

realm=coturn.meetrix.io
fingerprint
listening-ip=0.0.0.0
external-ip=127.0.0.1
listening-port=3478
min-port=10000
max-port=20000
log-file=/var/log/turnserver.log
verbose

user=my_username:my_password
lt-cred-mech

• otherwise, use your server's public IP in 'external-ip' and 'listening-ip'

config Signaling server

• make these changes in flutter_webrtc_server/configs/config.ini

[turn]
public_ip=127.0.0.1
port=19302
realm=coturn.meetrix.io

• Use your TURN server's public IP above (if not localhost).

Changing the project code

• in src/signaling.dart where there is this code

_iceServers = {
         'iceServers': [
           {
             'urls': 'turn:127.0.0.1:3478',
             'username': 'mohsen',
             'credential': 'mohsen',
           },
         ]
       };

• change it to your turn server's public IP and use the username & password you set here .
  • When both servers are local, use the IP of TURN server, seen by Signaling server.
