There's no mistery to cross a router, most apps use UPnP in their local app to configure and keep open a routable port on the NAT router. Other solutions have existed but now UPnP is almost uniersally supported by most routers and users don't have to know their IP. Instead they renew their subscrip

I've looked at serval and its a mesh network that has some complexity and its not as reliable as one might desire. It's better at text messages than phone calls especially if there are delays in getting across the network. Also it really needs a special router with custom software. They recommend

Hi John, Hi Philippe, Thanks for the post. I'd written this reply before Philippe posted, but not hit sent, sorry. Let me send it anyway. To explain further: Unless one router extends the network of the other, each phone would be behind a firewall created by the router. So you'd have to place the
