(author here) I've used SimpleWebRTC[0] in the past with success. It was helpful once I needed to start dealing with the annoyances of cross browser compatibility, multiparty calls, etc. You can also fork their code on github[1], which is what I ended up doing.
Thanks for the nice writeup. You mentioned Javascript in the article. Is webrtc tied to browsers and JS? Or can it be used by other clients too .. like mobile apps or wearables?
Can you clarify the use case? For client side use, PeerJS [0] (a bit old though), simple-peer [1], and SimpleWebRTC.js [2] are friendly abstractions (and you'd use publicly-provided stun/turn servers). If you need to do more advanced stuff instead of client-to-client, there are a couple server-side impls, but it's not a common use case.
Although this doesn't quite answer your question, I had a lot of fun playing with TogetherJS a few years ago; it made taking advantage of webrtc for a collaborative web game/tool pretty straightforward.
I tried Tokbox and vanilla WebRTC (using SimpleWebRTC), and I'm still not convinced there are any benefits to the paid services (oh, they provide out of the box signalling? that's nice, that's a one-time cost, along with setting up your own STUN/TURN servers). It's like using Red Hat Linux enterprise edition instead of the free Ubuntu (or should I say, CentOS?).
The thing is, these SaaS companies that simply wrap WebRTC up and sell it don't take you very seriously if you are not a big client. It's pretty frustrating when your customers have issues, and your only interface with a black box is through T1 support who is just asking you to do stuff you already know to do because it's on their script ("have them refresh their page") rather than actually fixing the problem.
With SimpleWebRTC, it's a bit more work, but I'm able to actually dig into issues myself and fix them whenever my customers have problems. Tokbox is more for someone who doesn't want to take time to grok the contents of the linked article and who has a large enough budget to pay for their enterprise support.
