That’s controlled by this function. :-)

And its cousin, the global parameter (on the same docs page):

Thanks Alex. I didn't have this parameter "reply_to_via" set.
The documentation says that this parameter controls the IP address to which the reply is sent.
But what of the port ? it seems the port from the "Via" is always used to send the reply.

Hello,
I’m using Kamailio in stateless mode to send redirect responses. I’ve noticed that the responses are sent to the packet source IP address, and to the port found in the Via header.
I’m a bit confused. I was expecting the response to be sent to the address and port found in the Via header.
Is it the expected behaviour ?
I’m using Kamailio 5.5.2.
Thanks for your help !
Regards, Nicolas.
