Thanks, Bodgan-Andei.<br><br>But unfortunelly, for UDP, that only work for the transport port. For example, if I send the request from IP_A:PORT_A and I specify IP_B:PORT_B in top most via, the reply is sent to IP_A:PORT_B.<br>

Hi Victor,<br>
<br>
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.<br>
<br>

Thanks, Iñaki. But It is not what I really need.<br>
<br>
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.<br>
<br>
This is, basically, in order to perform NAT discovering and typing from the server.<br>
<br>
Thanks in advance,<br>
<br>

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

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

Hello to all,<br>
<br>
About SIP/UDP: Is there any way to specify the IP address<br>
for SIP responses, in a similar fashion as port specified<br>
on top most Via HF?<br>
<br>
Thanks in advance,<br>
<br>
Víctor<br>
