I don't understand. 1:1 means two people. What's wrong with using "group chat" with a group of two people? I don't think even XMPP focused on 1:1 and even Slack uses XMPP (or at least used XMPP in the earlier versions, as it started out as an internal communications solution built as IRC + storing messages in database + search + ...) Also, https://meet.jit.si https://meet.jit.si , https://jitsi.org https://jitsi.org They also use XMPP.
