Jitsi seems excellent within its limited functionality. It's what Signal's video calling ought to be [The right aspect ratio - Ed], and works admirably well for one-to-one calls. Zoom seems to have the edge when you've got lots of people and need to worry about keeping the interpreter on screen, or screen share or whatever. The lack of a proper desktop app is irksome.ETA: Jitsi appears to have developed a screen sharing feature since I last looked. Will have to investigate that...
