How to self-host to not rely on WebRTC STUN server stun.l.google.com:19302?

Question

I have just downloaded a video chat project. It uses a STUN server and specifies the URL stun:23.21.150.121. How can I use my own server instead of the STUN ser

Answer 1

This is the new way to config STUN and TURN in RTCPeerConnection initialization. Below is the working mode from apprtc.appspot.com

var peerConnectionConfig = {
  iceServers:[
    {urls: ["turn:173.194.72.127:19305?transport=udp",
       "turn:[2404:6800:4008:C01::7F]:19305?transport=udp",
       "turn:173.194.72.127:443?transport=tcp",
       "turn:[2404:6800:4008:C01::7F]:443?transport=tcp"
       ],
     username:"CKjCuLwFEgahxNRjuTAYzc/s6OMT",
     credential:"u1SQDR/SQsPQIxXNWQT7czc/G4c="
    },
    {urls:["stun:stun.l.google.com:19302"]}
  ]};

Actually there is no need to setup your own STUN or TURN servers, because there are a lot of public/semipublic servers. STUN from Google not always works very well.

This is my latest verified list (don't forget stun:/turn: scheme in URL):

{url:'stun:stun01.sipphone.com'},
{url:'stun:stun.ekiga.net'},

In case if you need your own STUN server, you can use this one written for Node.js, or find some here.

Also you can check this and this pages for better understanding.

Answer 3

EmerCoin has large list of public STUN servers: http://enumer.org/public-stun.txt You can use any of them.

Answer 4

There are a few options to set up your own stun server. There is the rfc5766-turn-server. Once you set it up on your server, you can use that server's IP address and port you have set it to listen to. You will need some basic linux sysadmin knowledge for this.
