Hi,

>>I don’t know if you left the following out by mistake, if you assumed the issue had been solved, or if I simply missed it, but just in case:
>>
>>DTLS-SDP: "the offerer and answerer generate their own local 'tls-id' attribute
>>values, and the combination of both values identify the DTLS association."
>>
>>JSEP: "If this is an answer, the tls-id value, if present, MUST be the same as
>>in the offer.”
>
>That was my "Issue 1b":
>
>(Issue 1b) Additionally the final sentence of that bullet ("If this is an answer, the tls-id value, if present, MUST be the same as in the offer") conflicts with the definition of >tls-id ("the offerer and answerer generate their own local 'tls-id' attribute values, and the combination of both values identify the DTLS association"). In this case, the DTLS->SDP document would appear to be correct (the fact that the two parties choose different IDs is integral to the mechanism's design), so JSEP needs to change.

Correct. My mistake.

Regards,

Christer
