ICE candidates will only tell the end point that UDP vs TCP,. Kind only tells the type of stream. If there is more then one way to transport this data (SCTP vs QUICK), proto is required. I understand your points, and you are right in all of them. I just don't believe that this is gonna happen in SIP world within next 25 years. I mean: in order to explain this you have moved to DataChannels, which will never exist in SIP-land (BFCP already exists which is implemented by 2-3 devices). > Also, you ignored the question that I asked you.

Please read second bullet point of https://tools.ietf.org/html/draft-ietf-mmusic-ice-sip-sdp-24#section-3.2.5 Didn't know that. Thanks. -- Iñaki Baz Castillo <ibc@aliax.net>
