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 -

1) Reduce UDP packet size to avoid MTU limitations

2) 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
