Thanks Fred, works like a charm!

Might be worth adding to https://www.kamailio.org/wiki/tutorials/security/kamailio-security in the same section as masking the Server header. I never considered the cookbook for this, I’d gotten the original idea from the security suggestions page!

Thanks again :).

You can make it global with:

user_agent_header="User-Agent: My Super SIP Server"

Hi all,
I’ve set the server_header variable in my primary config, and I’ve got a catch in the default reply route to modify headers where required. I’m masking this value for security reasons, and filling it with my own value for vanity reasons :).
I’ve noticed that the OPTIONS packet that is send via the dispatcher module when probing mode is on contains a User-Agent field which has the full version and OS type. Unfortunately I don’t necessarily have trust of the end destination being dispatcher to, nor the packet switchers in-between.
How can I catch this OPTIONS packet to manipulate the value? It doesn’t appear to go through the REQUEST route or the ONSEND route.
Thanks!
