Hi Suhas,

One more thing that was discussed with Christer but did not make to
sctp-sdp was what should be specified in session descriptions m= line
during the ICE nomination process. Christer correctly pointed out that this
belongs to ice-sip-sdp. As it stands right not it is unclear if default
candidates should attempt to match currently selected candidate pair or
continue to send the original default candidate. Trying to match currently
selected pair can be difficult, especially since it can change during the
signaling exchange and you can end up with m= line transport mismatch. My
proposal was:

Session descriptions sent during the ICE nomination process SHOULD include
all the candidates discovered during the ICE nomination process, ICE
candidates present in the session description that started the ICE
nomination MUST not be removed from the session description and the default
candidate MUST not change until ICE nomination process is complete.


Finally, there was a bunch of calls for defining ICE/ transport tag. Should
I propose the language for this for draft-ietf-mmusic-ice-sip-sdp or should
it go into the separate draft?

Regards,

_____________
