We tested it in a lab without internet connection (wire removed). A switch that emulates an internet network (ie, internet addresses), but isolated, two routers, two separate local networks, some standalone voip hardware phones. No turn server anywhere, no connection to internet. And no firewall or NAT, so you were on the same unprotected network, two different segments, but the same network.
Apples and Oranges Carlos.
This was on a private network and yes there was a firewall between the network at the various sites and the Internet. However, as I pointed out a few times now, the connection between sites was via VPN. The VPN terminates on the router, where the firewall rules are set up. But the VoIP traffic never passes directly over the Internet.
???? you should try typing less and reading more
It is always carried via VPN. So, there is no way into that network, except as allowed by the firewall rules. And you'd never see VoIP traffic on the Internet connection as it is hidden by the VPN. Regardless, there is still no NAT involved between the different locations, thanks to the use of the VPN. No NAT means no STUN.
