I know it’s not seen as a professional service, but Discord has great quality video chat (better than Zoom, for example). I don’t know if its privacy/security would hold up for larger companies but we use it in my tiny company with no issues at all.
Any recommendations on getting Discord notifications to reliably show up in a reasonable time on mobile? That's the one big issue I have with Discord. Otherwise I find it very useful.
If you have the desktop client up, you don't get mobile notifications. They've always worked fine for me so long as I don't set my status as do not disturb
