Hi, >> DES F7 If an answerer that does understand the bundle mechanism >> processes an offer that contains a bundle, it must be able to (1) >> accept the bundle and selectively accept or reject each >> constituent RTP session within it, (2) reject the bundle as a >> whole, or (3) reject the bundling and selectively accept or reject >> each constituent RTP session as separate RTP sessions. > > If you with "constituent RTP session within it" where it is a bundle means the RTP media streams resulting from that particular SDP media description (m= block) then I believe I agree with 1). Agree. It shall be possible to reject/accept each m- line individually. > When it comes to 2) what makes this different from rejecting each m= block within the bundle? Agree. Putting the port to zero is the SDP offer/answer mechanism for rejecting an m- line, and bundle doesn't change that. > 3) is required if legacy fallback at all going to be available. As currently specified, this is achieved by sending a "legacy" SDP answer, without bundle. Regards, Christer
