Hi, for now, the "normal" way to detect if an in-dialog request/response beyonds to a natted dialog is by adding a uri parameter ("nat=yes") in the "Contact" header of the first request and response and macthing that parameter in the RURI of subsequent in-dialog requests.
instead of contact header, you could use rr header.
Yep, in fact finally I used "rr" :)
