Hi,

We seem to have an agreement that, when an SDP offer contains an m- line associated with a bundle group, it is ok to leave that m- line outside the bundle group in the SDP Answer.

Now, there has been some discussions about "splitting" a BUNDLE, meaning that an m- line in an SDP Answer is added to a DIFFERENT bundle group than in the SDP Offer.

Based on the discussions, it seems like people would be ok to NOT allow that. If the SDP Answerer wants to put an m- line in another bundle group, it needs to first reply to the SDP Offer, and then send a new SDP Offer itself, putting the m- line in the bundle group it wants.

In short, is basically means: in an SDP Answer, an m- line must only be bundle grouped with the same m- lines (or, a subset of those) as in the associated SDP Offer.

Regards,

Christer
