From what I saw, Nat´d por does not change. It always use 52548.

Questions:

1 - In order to get rport, as you mentioned, i can use transformation. ¿What variable / pseudovariable I can use to get a string that contains rport?

2 - After I get that info, what would be the best way to insert that info in kamailio.cfg file

3 - After updating the file in some way, how can I restart the service?

and last but not least, Is there a more elegant way to do this? I am feeling like reinvent the wheel.

Thank you for all your support

To get rport you can use transformations.

If you restart kamailio, is the firewall preserving the same value for
rport?

Cheers,
Daniel
