I've been working on this project for a while now and have no other solution but to turn to you guys.
I setup a STUN/TURN on Azure VM. The setup of the server is as follow:
listening-port=3478
tls-listening-port=5349
fingerprint
user=user:pass
lt-cred-mech
realm=kurento.org
log-file=/var/log/turnserver.log
verbose
external-ip=<Public_IP>
On the VM on which KMS runs, I configured the file :
/etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini
With these modifications :
stunServerAddress=<public_ip>
stunServerPort=3478
turnURL=user:pass@<public_ip>:3478
In the client , I setup the RTCPeerClient with these options before getting the user media and creating the offer.
const configuration:
RTCConfiguration
= {"iceServers": [
{
urls:['turn:<public_ip_VM>:3478'],
username: "user",
credential: "pass"
},
{urls:['stun:<public_ip_VM>']},
],
iceTransportPolicy: "all"
};
I then join a call in one browser and join on another.
Here are the complete logs for the first browser that joins the communication:

You can see that the iceconnectionchanged results in a state of "checking"
Whereas in the second tab that I join the call session on :
