In Matrix 2.0, all calls are group capable (much like Matrix itself doesn’t specialcase DMs - they are just rooms with 2 people). So yes, no coturn is needed. We haven’t got as far as interop between legacy Matrix 1:1 calling and Matrix 2.0 style MatrixRTC though, which I can see being annoying - but overall the admin burden should be simpler than running a coturn. We’ll update the synapse docs to explain that coturn isn’t needed for MatrixRTC calls.
