If your Kamailio setup is close to vanilla, it should do it by default. But Kamailio is a very powerfull tool, it can easily be setup to stop passing over ACKs :)
To attempt to answer what explicitly sends along the ACKs, that will most likely be the t_relay function, together with the logic which went before it… A good old tcpdump will most likely enlighten us.
