Web Call Server 5 is a nightmare and doesn't work
Web Call Server 5 is not ready for production and doesn't work.
We could not deploy a workable RTMP or TURN/STUN signal/relay for our Live video streaming app.
There is no free trial so you will be CHARGED for testing this terrible software. It was a nightmare deploying, testing and trying to installing encryption certificate like Letsencrypt. etc. You must be an experience EC2 User before testing this. It was a complete waste of time and money.
