[MMUSIC] BUNDLE: SDP O/A Open Issue: Allowed for Offerer to assign same address to multiple m- lines before Answerer has indicated BUNDLE support in SDP Answer?

[Christer Holmberg <[e-mail]>]

Hi,

In BUNDLE-04, there are a couple of open issues associated with assigning the same address to multiple m= lines in a BUNDLE group.

The main technical issue is whether it should be allowed to do it *before* the Answerer has, in the SDP Answer, indicated support of BUNDLE.

I.e. should it be allowed to, in the *initial* SDP Offer, assign the same address to multiple m= lines in a BUNDLE group?

Paul has indicated that it should be allowed, if the Offerer e.g. "knows" that the environment where it is operating in supports BUNDLE.

Now, as that is very similar to my original BUNDLE proposal, I would like to hear what others (especially Cullen) thinks about it.

Regards,

Christer
