Hi,



Ok, my misstake, I thought you were talking about only sending the 1st Offer with unique addresses, and not sending the 2nd Offer with the shared address.



So, what you are talking about is the original BUNDLE proposal (before it was merged with CUNDLE).



Regards,



Christer

That's what I thought we were talking about. This has the benefit that you don't need to gather STUN/TURN for the other addresses that you know you are going to discard.

Regarding intermediaries, I expect that even for less-well-provisioned WebRTC app providers, there typically won't be any intermediaries, at least none who have access to the signaling traffic.

Exactly.  That's what I'd do.
