actually, push-to-talk voice memos do work Gajim. An underrated feature!
Prosody allows voice and video calls - I have a TURN server all set up with it - but QOS rules (which are beyond my control, and are the fault of the ISPs I use) can sometimes squash calls made.
Gajim 1.9.3 (Flatpak) seems support voice and video calls to Conversations, but then it doesn't work. One Conversations smartphone can make voice and video calls to another Conversations smartphone.
