We should have sound effects for when certain actions happen in the call. imo, at a minimum we should have:

• An audio cue for when someone joins the call (to prevent the awkward case where you're waiting for someone in another tab and they stare at you for a minute before saying hello)
• An audio cue for when someone leaves the call (though potentially become inspired by Jitsi where after a certain size of call the join/leave effects no longer play)
• An audio cue for when you've clicked the hangup button, to give confidence that you've actually left the call and aren't broadcasting your camera to the world still
