Having great experiences using npub16rd8lagwh224jkyu3v5vehkjtnxmz7t7zfuc9ltsg04qpp87xc7sfh3v3k (npub16rd…3v3k) #nextcloud #nextcloudTalk !
I've had video + screenshare calls with 5 of us without any problem. I did have to setup a coturn for one participant, and I'm aware that it's not going to scale efficiently without significant funds, but a lot of my meetings are up to 5/6 people, so that's great.
I've had better reliability (inc. screenshare) than with google meet, zoom, signal, or teams.
