>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
To get rport you can use transformations.
If you restart kamailio, is the firewall preserving the same value for
rport?

I am thinking that I cat get the port during the first call and then use
that port for the rest of calls.
Maybe that first call will fail but after that, all calls will go fine.
Example of a Trying showing received port: 52548
¿Do you know what pseudovariable represent that value?
I tested with
Ahh, I thought Asterisk is in the public internet, but actually you
connect to a provider (vendor), which seems to run Kamailio as well.
Using information from 100 trying is too late, as the INVITE was already
sent... so one more question before trying to propose a solution. Do you
have to registe
Yes it is possible, but is there an easy way to workaround the issue using
Kamailio.
Because I have the port because vendor is sending that info in Trying:
2016/01/13 20:10:15.842055 VENDOR-IP:5060 -> PRIVATE-IP-KAMAILIO:5060
SIP/2.0 100 trying -- your call is important to us
Via: SIP/2.0/UDP PUB
Not really up to date with all Asterisk features -- do you know if you
can append a custom header to a SIP response that is going to be
generated by Asterisk? Eventually the reply for an OPTIONS request.

Yes, I manage all devices, even the internet router but it does not allow

Do you control the Asterisk? If yes, depending on Asterisk capabilities of
building replies, you may be able to do some automation to detect the
external port.

There is not a public Kamailio, only one Kamailio behind NAT,
Right now the configuration is:
Asterisk <-> Kamailio (Private IP + advertise public IP + RTP Proxy ) <->
Internet router (public IP + symmetric na) <-> Internet

Is the kamailio behind nat communicating with another kamailio on a public
IP?

Thank you Daniel for your answer,
As you mention, there is a symmetric nat and router does not allow a static
NAT.
By sniffing traffic I can see the port is using new but in case it change,
how can automate the process of advertising the correct port?
Cheers!
