This is a fascinating and well elaborated article!

I noticed that UX/UI is important and a guarantee that SAS should increase in length, what are some of the recommendations that you advise to have a good ZRTP implementation ?

Or should we start discussing the fadeoff of ZRTP and a change to something like Matrix protocol or even Signal's one ?

Both Matrix and Signal use WebRTC for VoIP so the content is encrypted by default. Call set up and signaling is also encrypted by default with Signal, and possible with Matrix - it's automatic if the room from which a call is established is already encrypted.

I know Signal attempts to prevent any data leakage by forcing the Opus codec to use a constant bitrate instead of its default VBR -- I'm not sure if Matrix implements anything similar yet.
