Apologies if this question was already asked, I could not find good answer here but maybe I was not using the right keywords.<p>I would love to host a system for my family (including my grandma who is not very technical) and friends that would let us communicate over messages and audio calls (if video calls would be possible then I would be in 7th heaven)<p>Can you share what you are using (if you have done something like that)?
Others have mentioned very good choices for messaging. For self-hosted audio and video calls, another option is OpenVidu Call: <a href="https://openvidu.io/openvidu-call" rel="nofollow">https://openvidu.io/openvidu-call</a><p>(that page also includes a demo deployment)
Self hosted Matrix server? They also use jitsi for voice and chat, so I don't know if you have to set that up separately. Maybe they have an ansible role or docker-compose that does both.
