Hi, Sorry for missing the other changes. I think I gotten all the lock down changed now. This has resulted in some significant changes in the text for TURN relays, including a server implementation requirement. I recommend that people do take a look at the diff: http://www.ietf.org/rfcdiff?url2=draft-ietf-mmusic-rtsp-nat-evaluation-08 Cheers Magnus On 2013-05-23 19:58, Ari Keränen wrote: > On 5/23/13 5:47 PM, Magnus Westerlund wrote: >> On 2013-05-17 17:49, Ari Keränen wrote: >> >>> >>> >>> 4.9.1.
