Please, let me know which exact subject should I report to AVTCORE WG.
AFAIU draft-ietf-mmusic-sdp-bundle-negotiation is being done here in
MMUSIC WG.

If what I say in my previous email is true (maximum of 16 audio+video
participants in a WebRTC multi-stream SFU conference) I think there is
a big problem in BUNDLE, and hence in MMUSIC.

Thanks a lot.
