Hi,

…

>>I hope at least we can agree that an JSEP Answer MUST use the PROTO string of the OFFER?
>
>Yes. I think implementations should offer UDP/ (ICE/ will cause problems) and in the answer echo the offer.

This is related to the generic issue I raised in Seoul, and sent an e-mail about last week: is it ok to echo the transport in the m- line proto value of the answer even if the answerer doesn’t support the transport (alt #1)?

OR, should we mandate a transport that everyone must support, and mandate to use that transport as m- line proto value in offers and answers (alt #2)?

People in Seoul preferred alt #1, but I know that at least Roman prefers alt #2.

Regards,

Christer
