You do not have super cow powers, and neither do I. SIP is not just a toy for home users willing to replace their cheap router with a new one. Even with IPv6, Firewalls will not go away. So what? Switch them all off? Set up static rules for each SIP device? Did you ever look at all those transition methods for IPv6? Still sure, that NAT will go away? Really? With IPv6 you WILL need ICE, more than ever before. You will also have to deal more and more with mobile devices, connected to many completely different networks (UMTS, WLAN, LTE...) - some of them may be under your control, others will be not. Try to see the big picture - SIP is far more than just a few phones behind a cheap router, connected to a "provider server" (whatever this would mean). RFC3261 was a giant step forward, but was still missing many pieces of the big puzzle. But slowly this picture is getting more and more complete, with ICE being one very important piece of this puzzle! But, once again - my question was NOT related to ICE, it was about UACs able to do nothing but plain old STUN :( Regards, Thomas Gelf -- mail: [email protected] web: http://thomas.gelf.net/
