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.

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. -----Message d'origine----- De : sr-users <sr-users-bounces(a)lists.kamailio.org> De la part de Alex Balashov Envoyé : jeudi 27 octobre 2022 18:35 À : Kamailio (SER) - Users Mailing List Objet : Re: [SR-Users] Kamailio sending response to source IP and port from Via ? ***This mail has been sent by an external source*** Ni Nicolas, This behaviour is regulated by: https://www.kamailio.org/wikidocs/cookbooks/5.6.x/core/#reply_to_via — Alex This message contains information that may be privileged or confidential and is the property of the Capgemini Group.
