Hi,
I am setting up Raspberry Pi to run Kamailio with mediaproxy-ng. This
machine is running on local LAN behind a DSL router. Using dynamic DNS and
DMZ services of router, i can access this box from the Internet.
However, i do not know how to define advertised_address parameter to public
IP of router. The public IP is dynamic and changes roughly every 12 hours
or so. Is there any way kamailio can automatically learn this dynamic
public IP and use that as advertised_address?
Something similar to Asterisk's res_stun_monitor module,
https://reviewboard.asterisk.org/r/854/
Any help will be greatly appreciated.
Thank you.

Not inherently. But you can devise some external process (e.g. cron
job, script) to accomplish this.

A wiser idea, however, would be to run Kamailio on a real, public
server, not behind

Yes, I can either move to static IP for router OR bind kamailio with
ddclient, so that whenever ddclient reports an IP change i restart kamailio
with new advertised_address. But these are out of the box solutions. I
wonder if we have any "in-the-box" solution. :-)
Thank you.

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.

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.
