Yup, that's a WebRTC thing.

Arthem here, @seth feel free to let me know if you would like any help with the project. Seem pretty interesting. I am available for contact on reddit /u/arehmat .

I have extensive experience developing software for video and audio calls over WebRTC. Firefox and Chrome pretty much always work the same. Safari, desktop and especially mobile (iOS) almost never works.

Edit:

Safari is by far the worst browser in existence. Unfortunately we're stuck with it until the USA Congress says otherwise.

I know that "politicians suck" but we can't blame them for Safari!! Safari will stay around for as long as it serves Apple's interests. My personal choice is Firefox. But that's just me. People can use their own browsers in many/all OS, so feel free to ask your clients to use Firefox/Chrome/IE ;) and not Safari.

People/companies can always switch to Firefox/Chrome as they both have the capability for central administration.

Can you elaborate?

WebRTC only works on certain browsers and platforms.

WEBRTC is showing 94% support: https://caniuse.com/?search=WEBRTC

Can you elaborate on the Firefox support issue?

Honestly, the browser/platform test coverage isn't broad yet. Not too sure why Firefox is having difficult but I know some browser and platform combos are quite finicky with WebRTC.
