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!

Check record_route() in the default configuration script. You need to add a route
set by using record_route() in the initial transaction.

Thanks Olle. I am calling record_record() on the initial INVITE. In fact,
the OK has a Record-Route header:
1.1.1.1 is the endpoint
2.2.2.2 is the kamailio proxy

I don't think 3.3.3.3 should show up anywhere, it should be rewritten to

Why is erroneous to have the contact header with the backend IP?
With the record-route on the 200 Ok, the ACK should be directed to the
backend IP, but containing a route header pointing to the Kamailio IP.
Kamailio will loose_route() this request and send it to the backend server
as expected.

No, you are not dealing with a buggy client.
As Carlos pointed out, you are dealing with standard SIP loose routing
mechanism.
Time to read the RFC :)
