Yes. I defined advertised address and even used listen with advertise as below. Still
Kamailio does not send publicip in record route header.
listen=udp:MY_IP_ADDR:5060 advertise MY_PUBLICIP_ADDR:5060

Hi,
not sure if I understood it right but, have you defined the advertised_address ? That
should be used in Via and RR as well:
I implemented full NAT logic as per the sample config.
Still unable to
resolve the issue.
How do I let Kamailio change record_route header to use public ip address?
Please help!!!
(attached are latest scripts)

Hi,
I am encountering the same problem described in google groups
<https://groups.google.com/forum/#!topic/2600hz-dev/-xvUZUrv4Y4>.
However I dint not find any resolution hence writing again.
200 OK sent from the server has private Ip in its record route. As
you see below, though the message is received on public IP
(63.149.103.72) , the record route is set to private IP
(172.31.211.31)
I used listen with advertise of public IP, it did not work. Please
find attached the config I am using.
How do I change it send public ip only when talking to external world.
Can someone point to me clear documentation how to configure
Kamailio for NAT traversal.
