[SR-Users] Fwd: Kamailio and NAT

[Nelson Migliaro]

>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
