At that point the conversation will be encrypted, both audio and video.
However, you are responsible as a participant to check the SAS and authentify
the peer you are communicating with.

If picto, SAS and remote peer authentication are handled correctly, then you 
can be
sure that the communication is trully end-to-end encrypted.

In this case both participants should validate the SAS which will allow 
automatic
checking for future communications with the same peer.


Cheers,
Guillaume
