Hi Victor,

if a UAC wants to have asymmetric signalling, just send from IP_A:PORT_A and put in top most via IP_B:PORT_B - via is used for routing back the reply.

regards,
Bogdan

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.

This is, basically, in order to perform NAT discovering and typing from the server.

Thanks in advance,

Víctor

Actually not. What I need the UAS exactly to do is to send the SIP
reply to a different IP address than the source of the SIP Request
that it is replying to. Just how it sends the replies to the UDP
port specified in top most Via HF.

Hi Victor,

Not sure I got your question correctly, but you mean like
something like "received" via param used to route back the
replies?

Regards,
Bogdan

Hello to all,

About SIP/UDP: Is there any way to specify the IP address
for SIP responses, in a similar fashion as port specified
on top most Via HF?

Thanks in advance,

Víctor
