Re: [discuss-webrtc] WebRTC UA, Without STUN/TURN servers, non-local media still shared correctly?

[Kaiduan Xie]

Because Asterisk is on public IP, Asterisk can figure out the NAT address of the webRTC client behind the firewall even though STUN is not used in the webRTC client.

Without Stun/Turn servers configured, the only candidates you might get from onicecandidate are "host" type, which technically is your local ip address.

For my case :
type:host # address:192.168.1.56 # port:57934
type:host # address:192.168.1.56 # port:9

I have a WebRTC UserAgent (SIPJS Library) behind a firewall, connected to a B2BUA (Freepbx to be more precise) via 8089 wss for signaling. The asterisk server is cloud based, with a public ip address (No stun).

I have not configured any Stun/Turn Server on my SIPJs peerConnectionConfiguration, and still my webRTC client is able to share RTP media with Asterisk with no problem.

How is that possible ? is there any built-in stun server on the browser in case no stun server is configured ? Do i really need a Stun server in such use case ?

Thank you

That all depends on the network where the webrtc client locates. If the network blocks UDP, and Asterisk does not listen on TCP, then you still need a TURN server.

In other words if my Asterisk is on public IP , i dont need to use any Stun/Turn servers on my webRTC clients ? is it safe to disable it ?
