Marrold,
No, you can't remove those headers. They serve an essential purpose and the endpoints won't consider the requests or responses valid without them.
See my blog post on this topic:

And you certainly can't hide topology this way.

Hi,
Is there any way to remove Via and Record-Route headers from requests sent to an endpoint and update the contact header, but have Kamailio statefully remember where the replies need to route?
I imagine this would involve mangling the packets slightly to behave similar to a B2BUA.
My motivations, in order of priority -
- Reduce UDP packet size to avoid MTU limitations
- Improve interoperability, don't expect end points to be able to
properly parse / process many via / record-route headers 3) Hide topology.
If someone could point me in the right direction in terms of configuration or modules, that would be great.
Thanks
