AFAIK TURN is just required in case both endpoints are behind different symmetric NAT routers. IMHO there is enough cases in which this doesn't happen so ICE is really *suitable*. >In my humble opinion if proxying media is the answer Proxing the media is NOT the anwser. > why not just multiplex the media and the signalling in the first place, aka > IAX & Skype, Is IAX a good protocol? Does Skype *always* force the media relay through a media tunnel? The response to both questions is "NO" so not sure what you meant saying that. > ICE, a fix for a fix for a fix; RFC3261 not handling > NAT being fixed by ALGs being fixed by ICE. I don't understand this point. ALG breaks, in most of the cases, the SIP signalling [*]. STUN, ICE or server solutions don't help here as in many cases those kind of SIP ALG routers modify and break the signalling even if the SIP messages contain public addresses (due to STUN usage), so I don't think ICE is here to fix ALG's. ALG's just must dissapear ASAP.
