Hi Roni,

What is the way forward regarding the draft?

Especially regarding the parts that BUNDLE need, i.e. the offerer being able to map received RTP packets from the answerer, we need to get done.

Regards,

Christer

Hi,

>By no semantics we meant that it is just a token with no parameters that maps the RTP stream >(packet stream) to a description in the SDP m-line.

Well, then that IS the semantics :)

Is there a reason why you don't call the 'appId' attribute 'send-appId' instead?
[Roni Even] No reason and we may have a different name for appId, was discussed on the list. We assume appId is sent-appId

Also, assuming the previous answerer in a subsequent O/A exchange becomes the offerer, which attribute (if any) does it include in the Offer? You need to describe how a change of the Offerer/Answerer roles affect affects the usage.

[Roni Even] The current text talks about having the answer use the recv-appId as the appId.
We need to add text about subsequent offer/answer, do we mandate keeping current appId.

Other issue we have is if we need to send appId (send-appId) or can only send the recv-appId
