As a real-world point of view, SIP VoIP solutions including Ekiga lack a perfect solution for overcoming Symmetric NAT. STUN works nicely and automatically for port/cone-restricted NATs (and that, or in the case of no NAT, Ekiga just rules!), but for Symmetric NAT you need to have an outside server you can use to help your connection, you need to configure the settings manually and/or you still can't make the connection.
Only when TURN/ICE will be standardized and working Symmetric NAT can be workarounded automatically, but even then it will suck as all the data has to apparently be forwarded through another host anyway (and will someone provide such a server for everyone to use? maybe Google, though). S**** works around this by being a P2P program, not just a VoIP program, by using ruthlessly the bandwidth of other users even without them knowing about it.
I, for one, have a Internet connection using Symmetric NAT at home. But I think most home users (ADSL/Cable) don't have this problem.
