WeAreAllOne , 3 months ago Many years ago I used XMPP with Prosody and it was ok. You can setup some retention time for attachments and history depending on the space you have. There are clients for multiple platforms but not very much advanced vs competition. Security is good with omemo protocol. In so e clients you have to turn it on since it's not by default. Audio video calls on one to one is good as long as you setup stun coturn server. Android to iOS calls still in progress. Check out Snikket for an all in one solution. You might want to also consider Matrix (dendrite option ?) for your needs.
