Yes, I'm handling external IP with domain module, so I'm matching it
I'll try to do it this way.
Thank you, Daniel!

I have a question that arises in mailing list sometimes, but it is
still not clear for me how to work with this.
We have AWS instance with standard Amazon bi-nat, so basically
communication with external hosts works with
listen udp:ip:port advertise ip:port
But in case when we need to send external call to internal network by
internal ip addresses, we want to have internal host in record-route.
As far as I understand, basic recommendation is to use separate port
or internal address and select it with appropriate function.
Maybe it is more theoretical question, but can we do something to
generate correct record-routes and VIA for calls coming from external
network to make their softswitches happy, and still maintain internal
address in messages going to internal hosts, using single host and
port on Kamailio behind nat?
you can do also without setting advertise address for
a listen socket.
Just listen on local IP and then you have to use
set_advertise_address(...) to set the IP in Via and
record_route_preset(...) to set the Record-Route header.
Only that the config becomes a bit more complex, you have to add IF
conditions when to add private or public IP addresses there.
One thing I forgot: the public IP has to be treated as local IP (to
match against 'myself'), so you have to do conditions on it -- either
directly in the config conditions, or adding an alias or using domain
