I was told that Matrix/Riot is a good alternative to Jitsi (can share a meeting URL and offers E2EE). Does anyone have a data point here?
One-on-one calls through Riot _are_ encrypted, but only if made in a one-on-one direct chat.
Recently we added the option for people to use their own self hosted Jitsi instances, if they prefer.
(1:1 calls at the moment are normal WebRTC, directly over Matrix)
