I have Kamailio setup as a proxy in front of a backend server (Asterisk).
When I make a call through the proxy, the Contact header in the 200 OK
that is returned to the client has the IP of the backend server in it.
Thus, the client is sending it's ACK directly to the backend server.
Is there a special method to rewrite the Contact header to be Kamailio's IP?
Where is a good place in the config to do this? (my config is loosely
based on this:
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb)
Thanks!
