Sandstorm.io community members host weekly meetings on Jitsi and have for a few months. It's not perfect, but it works and it's open source, and that's great. I will say the audio on a computer is a bit hit and miss, I often opt to dial in with my phone instead, which works pretty solidly. A really nice perk is that you can have your room name URL, and the dial in number is the same for that URL, so if you reuse the same "room", you can just know the meeting ID and all, which I haven't really seen from other solutions.
