          2. draft-ietf-avtcore-cc-feedback-message-02   - Colin
          
              Re: RFC6679 relationship: Jonathan says, must not offer both, answer
              picks one
          
              Bundle Discussion from Hackathon, needs some expertise to verify,
              but probably should send to all.  Zahed volunteered to get such an
              expert.
          
              Negotiation of feedback mechanisms - many feel answer selects one,
              but some believe answers with more than one should be allowed.
              Noted that subsequent offer may come from another entity so,
              send the list again, but don't gratituitously change the answer.
              Someone should send text to Colin
          
              Mo wants NACK text (if not ACK, NACK)  CCFB does not imply a
              retransmission request, NACK is required.
          
          3. Payload status - Roni
          
             flexible-fec has a problem, was discussed with authors, and will have
             more discussionm in the evening.It may need a substantive change that
             could not reasonably be done with an editors note.
             AD changeover affects this.  Have to see what comes out of the
             discussion.
          
             Media types should also be registered in rtp-parameters but are
             not actually syncronized.There are differences in policy between
             media-types and rtp-parameters. Needs to be addressed.
             Possible that the rtp-parameter registration is not necessary, but
             RTP experts need to be engaged if it is to be used with RTP. Problem
             is how to do that.
             Possibly the "framing" option was intended to be that, and isn't
             working.  Barry and Colin to investigate.
          
          
          4. Adjourned
