TURN is one way of getting external help, indeed. It's also
yet another step to endure the pains of IPv4 and NAT.
I am taking another angle, curious if you like it:
- switch to IPv6
- be sure to have IPv6 working everywhere
- enter 6bed4, http://devel.0cpm.org/6bed4
Note well -- the demo client is alpha, and may or may not work for you.
Extensions to the tunnel may follow in the future. But if you built it
into Linphone as a fallback you would not have to worry about NAT.
Anyone who is behind symmetric NAT must do something to overcome it;
one way is using an external helper like MediaProxy or TURN, another
would be to be available over IPv6.
I am porting 6bed4 to Android *now*, using the VPN interface.
