[Suhas] . It would be great if you can propose text to the ice-sip-sdp
draft since it needs to clarify on the transport tag and the default
candidate related issues that Christer brought out during IETF97. I have
the latest XML version pushed to github here

https://github.com/suhasHere/ice-drafts/tree/master/ice-sdp

Could you provide your proposals as PR here. I am happy to work with you to
incorporate them.
