Hello All Another issue or concern that was brought up is dealing with RFC5576 SSRC attributes across the BUNDLED m=lines. RFC5576 does allow SSRCs to be repeated across the m=lines given that each m=line forms a separate RTP Session. There were two options suggested in this regard (by Jonathan) 1. Don't allow SSRC values to be repeated across the bundled m-lines ==> Assign category NORMAL 2. Allow SSRC values to be repeated iff the media stream satisfies more than one m=lines, in which case, the individual sources define the behavior ==> We have 3 options here 2.1 Assign Category SPECIAL and add explanatory note on possible scenarios 2.2 Assign Category SPECIAL and propose an update to RFC5576 to explain behavior of a=ssrc attributes when multiple m=lines are multiplexed 2.3 Define a new category ?? I look forward for your inputs on how do we deal with this issue. Cheers Suhas
