Thanks again !
So if I want the reply to be sent to the source IP address and port, I have to configure
:
reply_to_via=0
force_rport=1
And if I want the reply to be sent to the Via IP address and port, I need :
reply_to_via=1
force_rport=0
If I configure nothing, the default is a mix of the two : reply sent to Via IP address but
source port.
It's working... but it's a bit confusing. ^^
Regards,
Nicolas.

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.
