Yeah that's the easy way to do it. But I think we can do it without coturn. Most of what coturn implements is for the old nat stuff. There days everyone has an IPv6. Só it should be easier.

"These days everyone has an IPv6" - don't think that's the case at all. Most countries seem to be running at around 50-60% deployment, and that's only showing allocated IPv6 that doesn't mean configured and in use.
That seems different than what I have but if that is true let's hope we can help them finish the transition.
Let's hope you can. It's been in deployment for ~20 years!
Maybe you're mixing cellular and fixed line services. On cellular, the figures are likely higher but on fixed line they're also likely lower. Mobile users aren't, most the time, using a cellular connection though, they're using WiFi.
