Subject: [MMUSIC] BUNDLE WGLC: Default candidate for bundle-only m- line with zero port value?

Hi,

One question that has been raised by Thomas Stach during the BUNDLE WGLC, is regarding ICE candidates and bundle-only m- lines with a zero port value.

The current text says that identical ICE candidate values are assigned to bundle-only m- lines.

Now, in the case where a zero port value is assigned to a bundle-only m- lines, it means that a candidate with a zero port value is also needed (in order to fulfil the ICE rules for default candidates).

IF we want to avoid that, a couple of alternatives have been presented:

1)      Do not assign ICE candidates to bundle-only m- lines with port zero. The problem is that the answerer, even if it supports BUNDLE/bundle-only, doesn't know whether the offerer wants to use ICE for those m- lines; or

2)      Relax the 5245 rules, so that there doesn't need to be a candidate matching the m- line port value.

Comments?

Regards,

Christer
