Hi, >I also did not get the impression that there was agreement on the m=bundle approach since there were a number of open issues. Ok. >As Cullen suggested in http://www.ietf.org/mail-archive/web/mmusic/current/msg09561.html, just offer a normal SDP, add a bundle line, and >assume the use of the connection information from the first m line. I agree with Cullen. This is what Harald origianlly suggested, and I raised issues with that solution. > I do not agree with the m=bundle approach for all the reasons Cullen mentions. The only thing I would add is that some networks may > require an updated offer be sent listing the correct port (the same one) on each media line if bundle is negotiated. ICE already requires > a 2nd offer in many cases, so I don't see this as a problem. I don't understand... The reason m=bundle came up was because people did NOT want to use the same port on each media line...
