Re: [SR-Users] How to hide Via and Record-Route header to external network and restore them to internal network?

Thanks Henning. I will try it. How topoh determines that it is a SIP message to be sent outside my network or not?

Vous ne recevez pas souvent de courriers de la part de hw(a)gilawa.com. Découvrez pourquoi cela est important<https://aka.ms/LearnAboutSenderIdentification> Hi Anthony, the restore happens internally and in the configuration you are able to access the headers, this is transparent for you. Just give it a try in your lab, you can easily see it on the network.

Hi Henning, Yes, I looked to topoh to hide topology but I didn't find a way to restore back the Via and Record-Route headers when I get replies from the external network.

They might be not doing exactly what you are describing, but usually are used for this kind of scenarios.

Hi Community, I have set up a SBC with Kamailio. I am testing voice call from external network to my network and voice call from my network to external network. When I send SIP messages to external network, I want to hide Via and Record-Route headers but when I receive replies from the external network I want to restore these Via and Record-Route headers to my network. How to store and restore these headers in Kamailio configuration ? Could you help on this? Thanks Anthony Blandin
