Caller <--> (internal_IP) Kamailio (external_IP) <---> Callee
I have this set up of kamailio with 2 interfaces.
i use topos module for topology hiding and what i want to do is to
send external_IP in Contact Header of request relayed to Callee and internal_IP
in Contact Header of response relayed to Caller.
i noticed that :
when i use topos module with contact_mode to 0
all Record-Route and Caller Via Header are removed and thats great.
but i dont find way to put 2 different ip addresses in Request and Response Contact
Header?
when i use contact_mode to 2 Record-Route and Caller Via Header are not anymore removed
thats bad for
topology hiding. And its seems we can not use $xavu(_tps_=>contact_host) parameter of
module
to put 2 different ip addresses in Request and Response Contact Header.
What i want is :
- remove all Record-Route and Caller Via Header for request like when contact_mode to 0
- and put 2 different ip addresses in Request and Response Contact Header
is it possible to achieve it ?
Thanks.

Hi,
I recently looked into this and I don't believe it's possible.
As a work around I used split DNS and an FQDN in the contact.
Thanks

Thanks,
I finally made it work.
i only needed to remove contact_host param so that the Contact headers for Caller and
Callee are taken from Record-Route.
