I can detect NAT during clients REGISTER, but not the type of nat (the
mapping reutilization method it uses). That's why I tried to do that: to
send a request from an transport address and receive it from another, so I
can check the source transport address to figure out if NAT is re-using the
same mapping.
Thanks for your help, Iñaki.

Thanks, Iñaki. But It is not what I really need.
I need to send to an UAS a SIP Request, like OPTIONS, and tell it to
send
the reply to a different transport address (IP
Addr + Port) than the
source
address of the request.
That is not possible at all, a UAS decides where to send the reply based
on
the "received" and "rport" values (if UAC indicated it) that the UAS
transport layer has set when receiving the request.
This is, basically, in order to perform NAT
discovering and typing from
the
server.
Is not enought to analize NAT during clients REGISTER? why you need it?
Regards.
