Hi Peter,

I submitted a new version (-27) of BUNDLE a few days ago. Could you take a look at the ICE Considerations section, and say whether you are ok with the text?

Thanks!

Regards,

Christer

That makes sense to me.

Hi Roman,

I didn't check whether some of the ICE attributes were session-level, but I agree with what you say: the same rule should apply to all media-level ICE attributes.

Assuming the scope is ICE, shouldn't the same still apply also to other ICE related attributes? I assume the values for the "remote-candidates",  "ice-lite", "ice-mismatch", "ice-ufrag", "ice-pwd", "ice-pacing" and "ice-options" attributes will be identical within a BUNDLE group, so...

"ice-lite" and "ice-options" are session level only candidates, so they should not be in the m= line BUNDLE or any other type. The same logic that applies to ICe candidates should apply to other media level ICE SDP attributes or things will break
