Subject: How to determine correct port to set in record-route header
Hi,
I am using Kamailio behind NAT, unable to figure how to make it put “public ip” in
Record-route header, I am manually inserting the hard-coded header myself as below.
However now I am having trouble choosing the right port number in all scenarios.
$var(dstPort) = 5061;
if (dst_port==5060)
{
$var(dstPort) = 5060;
}
insert_hf("Record-Route:
<sip:MY_PUBLICIP_ADDR:$var(dstPort);transport=tls;lr;nat=yes>\r\n",
"Record-Route");
In one scenario I see the conflicting port numbers in “via” header vs “Record route”.
The ACK is being set to port 5060 based on Record route header and is not being
received by the callee.

Questions:
1. How can I let in-built record-route function automatically choose “public ip” so I can
get rid of my manual insertion altogether.
2. If no option, what is the right way to choose the port on which packet is being
received, so it is same as what is on “VIA”.
3. Any other pointers to improve the logic here?

Take a look at https://www.kamailio.org/wiki/cookbooks/4.4.x/core#listen
and the mentioned set_advertised_address() / set_advertised_port() cfg
functions.
To quote the documentation:
A typical use case for advertise address is when running SIP server
behind a NAT/Firewall, when the local IP address (to be used for bind)
is different than the public IP address (to be used for advertising).

I have set that from the beginning, but of no avail.
advertised_address="63.149.103.72"
listen=udp:MY_IP_ADDR:5060 advertise MY_PUBLICIP_ADDR:5060

Hello!
Does anyone know if it is possible to pass variable
to set_advertised_address() function?
