Android Question Which best WebRTC ?

Dear all,

Greetings,

I hope to find best/simple WebRTC server.
I spent long time to find best and simple WebRTC server to access and run direct, found some but may for trial, others not complete and others require many many parameters to run.
Simply, from your experience of working, I need simple and best WebRTC which give me :
- Peer to peer,
- Video and audio streaming,
- Work between two users via Internet or even in same LAN.

Best regards
