Hi Roman,

Regarding offers for 3PPC, I think sending an initial offer needs to be a generic O/A rule. I don’t think we can have SDP extension-specific rules.

Regards,

Christer

Hi Christer,

I have reviewed the document and document changes look good in removing the inconsistencies with JSEP.

One question that I do have is related to third-party call control and generating offers in response to INVITE with no SDP body. This is not covered anywhere in this document. In order to work correctly thes offers should be constructed the same ways as initial offers with separate addresses and ports allocated for all m= lines which are not bundle-only and port zero and bundle-only attribute set on all the bundle-only m= lines.

Best Regards,
_____________
