Hello
using two sockets for internal and external traffic is the easier way.
The alternative is to use various functions from rr and core to set
record-route and via headers.
To detect what is the incoming local sockets, there are variables for
received ip, port or socket name -- see the pv cookbook.
Cheers,
Daniel

Hello! I wish everyone who reads this message a good day.
I would appreciate some guidance with the configuration of my Kamailio.
Initially, I have the following architecture:
Endpoints <----Public IP----> Kamailio (listen PrivateIP advertise
PublicIP) <----Private IP----> Asterisk
CONFIG:
https://gist.github.com/Carlos-Escalona94/3a289af05b05c69ae563ab29c9ec4710
In general, calls initiated from outside the system work perfectly,
but I have a problem with calls initiated from Asterisk.
According to what I was able to investigate and understand, the
problem arises from the fact that Kamailio uses the public IP for the
entire routing system that involves the Record-Route and Route
Headers. This in turn causes Asterisk to get lost trying to send
messages outside of the INITIAL INVITE transaction, for example, the
ACK response to the 200 Ok received from the Endpoint since it tries
to use Kamailio's public IP to which Asterisk doesn't have access.
I tried to force Asterisk to send all messages to Kamailio's private
IP regardless of their nature, but it doesn't seem like an appropriate
solution.
On the other hand, I tried to modify the architecture a bit so that it
was something similar to this:
Endpoints <---- Public IP----> Kamailio (listen PrivateIP:P1 advertise
PublicIP) <---- PrivateIP-----> Kamailio (listen PrivateIP:P2) <----
PrivateIP ----> Asterisk
CONFIG:
https://gist.github.com/Carlos-Escalona94/4d681bb189c6190941d291965e123889
It seems to me that this would solve the problem, but I have two
doubts about this architecture, the first is that I would like to know
if there is an easier way to solve the problem that I am not
considering, and on the other hand, I have not found a way to identify
from which interface is receiving the message to perform the routing
properly.
Thanks for the attention.
