            We have two deployments with PERC-Lite, one with VP8 and
            with Jitsi for Symphony and another one with VP9 SVC and
            Medooze. 
          

          [BA] Wow. That makes PERC-lite the defacto
            standard for Finance. How do you deal with the SSRC
            immutability issue? 

          
    The original rtp packet payload (without extension headers) is
      included in the outer encrypted payload, so any rtp params may be
      changed by the SFU as it would normally do. We proposed this to be
      consistent with perc double so it was less disruptive, but we have
      been working on alternative encryption algorithms with less
      overhead including full frame encryption ones.
