We've (IPFS community) have weekly open calls for the entire community and had great success with Zoom. I'm personally on Ubuntu, Arch and macOS, and everything is working fine and they continuously improve the software. Seems to have a free plan as well: https://zoom.us/pricing
Edit: adding that the few times I had to resort to using my phone, Zoom on Android has been working fine, even thought the UX is a bit confusing on mobile devices (Android version at least)
