[Freeswitch-users] Using FreeSWITCH as a STUN server

Discussion:

Hi guys,

WebRTC requires STUN servers to get the external IP address for ICE
candidates.

I would prefer not to rely on external STUN servers (google, etc) in my
production environment. Ideally I'd prefer to use the FreeSWITCH server I
need to connect to as my STUN server.

Is this possible? Can FS act as a STUN server?

Freeswitch can not act as a stun server, but there are a number of open source stun servers available that you can use. There is no reason for us to recreate the wheel when they already exist.

Hi Mike,

One reason could be to deal with symmetric NAT. However, it's not very
common, so I definitely see your point.

Right. Anyway I think you need TURN server for webrtc. I don't know if
webrtc run with stun only

Take a look at:

It does. I have a prototype with JsSIP and FS (FS with a public IP) that
works with just STUN servers.
