Based on some (admittedly very surface level) research, one spot where Zulip will still struggle to replace Discord is Voice/Video chats and Screensharing - the little I could find about voice chatting in zulip is that it has to be configured to use an external service (jitsi, zoom, etc)

If you do no configuration, it'll use the public Jitsi service for video calls. So no action required unless you want a different video call provider.
