If you looking for examples: you can use this one
https://github.com/havfo/WEBRTC-to-SIP as starting point

anyway, the Path mentioned by Alex is the best approach.

> Hello!

> I am trying to config one kamailio as reverse proxy for a bunch of

> I have used as starting point this very basic config:

> Basically just added rtpproxy support, and voilà, inter-SIP is

> The problem: I would have WebRTC phones connecting too. I tried setting
> WSS up in kamailio, and asterisk (pjsip) wouldn't know how to send the
> message to the proxy: on register it has trasnport=wss in the contact:
> header, looks like it is confusing the asterisk.

> So, I resort for the wisdom of the list :) What would be the

> Someone must have already made a blog with such setup, but I could not
