Not working on Android nor Browser: is the project maintained? Any successful implementation?

Hi everyone,

I tried the demo client/server to have a look at PhoneRTC, which looks wonderful as it is exactly what I need for my ionic app. However, it doesn't seem to work - at least from my few tries - on Android nor on Browser.
**Android** : I can connect and start/answer call, but no video nor audio stream. Plus, after 2 or 3 seconds, the app crashes.
**Browser**: I can connect and start/answer call, but no video nor audio stream. Yet I can see the output of my own local camera.
NB: everything is delivered through HTTPS, from the client app to the Nodejs/Socket.io endpoint

It looks like the project has not been updated for a while now, so I was wondering if the project is still maintained? And if anyone made a successful implementation of it in an hybrid app?

Thanks

Regards
