I could be wrong, but I would have thought that if a reply is being 
generated by Kamailio itself, statelessly or otherwise, then the ACK 
would be sent by far the end to the Kamailio host's address in the RURI. 
   Whereas an end-to-end ACK is addressed and routed to the other 
endpoint as a sequential request.
