There is if you have been configured to use TURN and are known to need to use it.

Hi,

Nothing prevents you from only sending host candidates in the first offer, of you want to do.

Subject: [MMUSIC] Bundle, TURN and Legacy Interop
Hi,

It seems that one of the motivations of the current bundle-03 proposal is that the first offer is compatible with a legacy device and that a second offer is required for bundle (See http://www.ietf.org/proceedings/86/slides/slides-86-mmusic-9.pdf).

One issue that I see is that if TURN is being used there could be a significant overhead in creating the first offer is multiple TURN allocations are needed for each m-line which will all then have to be released if bundle is used.

I am not sure if there is a way to avoid this other but the draft should I think mention this issue.

Regards
Andy
