How to begin Peer-to-Peer React Native?

Hello all I am attempting to provide peer-to-peer audio calls, and peer-to-peer video calls for my React Native app. I value data security and self-hosting and have found Wazo. I installed the demo react-native app but I cannot get passed the authentication stage

How do I sign up?

Further, what will be involved to set up a wazo server so my users can voice/video chat. It only needs to be 1-to-1 and there wont be any phone numbers.

Lastly, what is the pricing of this? and what does one need to maintain and pay for?

Hello,

For other people @stephanoparaskeva started another thread here: I think I have a bad SSL certificate and I cant authenticate a User in wazo-react-native
