Hi ,
I have a cloud server, when I make call from a sip phone (registered with kamailio),
in the INVITE header I am seeing the via header with public IP, is there any way that I can modify via header to send only the private IP.
The calls are landing on another sip gateway, they will allow only the private IP. 
Please let me know, is it possible to replace.

I tried all the replace functions but it is not working.

Thank you
