[OpenSER-Users] Saving public IP in CDR

[Andreas Sikkema]

Hi,

I'm trying to do add accounting to our OpenSER 
server. Getting accounting to work is easy but 
I'm having trouble saving client IP addresses with 
every CDR. 

Most of our SIP UAs are behind some form of 
NAT and to "prove" that calls have originated at 
the client I want to save the public IP address 
and as extra service also the private IP 
address of the UA.

Saving the private IP address is easy, $Ri 
contains this value. I'm having trouble finding out 
what to do to save the public IP address. I thought 
that since I'm using fix_contact() I could save the 
contact header body, but $ct still contained the 
private IP address.

Is this even possible?
