Just tested a voice call on #GNU #Ring for the first time (my Ring ID is 'strypey'). Worked pretty well. Not quite as good as #Wire, mainly because with Ring there was 3 sec delay, and I couldn't get it to stop echoing my own voice back to me, even using headphones and an external mic. More tweaking required (at my end or theirs)? Quite impressive though considering no server is involved. Client #UX isn't quite a smooth as Wire yet, but it has a lot of potential.
