And no firewall or NAT, Why not? Where you there to know what we did? LOL.
Try it yourself and educate yourself. Set the firewall, configure it. Set NAT, configure it. Make sure that VoIP works, learn when it does or does not.
As mentioned earlier, I have set up VoIP PBXs in the manner you describe where everything is on the local network. I have also set up some where the calls are routed to other offices, without passing through NAT and again STUN was not necessary. STUN is only needed when you have NAT blocking the proper connection.
Not even always. Asterisk worked with some firewall (ie, router+nat+firewall devices all in one) trickery. Only the asterisk server needed a fixed and known internet address. And nowdays, home /routers/ support VoIp facilitating things, including holes. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
