Which open source Webrtc voice framework is the community currently using that you recommend or at least give me some names so I can start a deep search.
For a user agent in the browser try jssip.
In this case, it would have to support an average of 400 to 500 authentications
I’ve heard that Asterisk can have a little problem with a huge amount of WebRTC connections in a short period of time. But the WebRTC client will run on the users device, and as such only have a single connection to Asterisk.
