WebRTC actually feels exceptionally tinkerable to me, with human(-ish) readable SDP offers, public RFCs, various implementations, and importantly it being accessible from JavaScript playgrounds right within the browser!

I've learned a lot about it over the years by following https://webrtchacks.com/, which does just that, i.e. taking apart various open and closed VoIP implementations (WebRTC or otherwise) and seeing how they work.
