Hi maxwell, what would you recommend to another developer who might be entering the same space with a WebRTC-based product?
I've stepped away but AFAIK they're still using it. It was expensive but worked with our business model ($20 for a successfully completed self-service video call between service provider and end customer, $50 to have the virtual survey performed/recorded by our trained video surveyors around the world, $90 to also have priced).
I'd compare TokBox, Twilio Video, and Jitsi.
The usual tools for cross-device/browser testing (e.g. BrowserStack) didn't work for video chat: we could simulate network disruptions but needed actual hardware for testing and debugging video/audio issues.
So we bought/pooled a ton of devices and had a QA team in our European office methodically test across devices and browsers.
We were also contending with provider (TokBox) issues early on in '15, which were mostly resolved by mid '16. Our business model, and pivots that focused our target market, didn't enable building out that level of infrastructure in-house, and I wouldn't recommend it if making any kind of vertical play, i.e. unless your customers are developers.
