You can send the info you need to Asterisk using X headers, for example:

Kamailio has the pseudo variable $si which contains the public IP originating the request and you can send that to Asterisk using append_hf.

append_hf("X-orig-IP: $si");

In Asterisk you can access the headers as ${SIP_HEADER(X-orig-IP)}

Hey, thanks for looking into this. Phones register with kamailio and I have configured kamailio to load balance the asterisk servers using round robin algorithm. Phones registered in kamailio will directly send the call to the asterisk servers. From there I will send the call out using other routes.

In the contact field of the sip header, I get the username@private ip instead of the public ip. I need it in the format username@public ip

In both cases, I am receiving the private ip of the user agent registered with kamailio. Do I need to change anything in kamailio to receive the actual IP address. Please suggest.
