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

[Henning Westerholt]

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.

Cheers,

Henning

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.
Regards,

Anthony

Hello,



already investigated the topology hiding modules (topos, topoh)? They might be not doing exactly what you are describing, but usually are used for this kind of scenarios.



Cheers,



Henning

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
