Yes, I agree. It is just an experimental setup to see capabilities of Raspberry PI as personal web sockets server (running kamailio) over LAN within a house for audio/video calls, media sharing etc. etc. (kind of replacement for DLNA). For that part it works great.

I was just thinking (at 0230 am in the morning here, hehe) of extending these services to connect to outside world e.g. to a group of friends houses (no commercial use), each house has its own server and can connect to a predefined list of servers for interaction.

Thank you.

Yes, I can either move to static IP for router OR bind kamailio with

Not that I know of. STUN and the like are client-side constructs, designed to be used by UACs, which Kamailio is not. A proxy does not endogenously originate messages (at least, formally), only receives and relays them, so the thinking is that other SIP elements should know how to reach the proxy, not that the proxy should be telling them how to reach it. Putting Kamailio behind consumer-grade DNAT inverts the envisaged client-server model.
