Yes :)
That exactly what I tested in the above URL:
  
https://sourceforge.net/tracker/index.php?func=detail&aid=2690374&group_id=139143&atid=743023

But it requires manual configuration. I think the behaviour defined in the 
draft is good for security and it should be implemented by default in 
Kamailio (without the need of coding it manually), and of course a config 
option to enable it (required in order to work as stateless proxy).

Don't you agree on it?

Regards.
