Hi Stefan,
Sorry for answering the wrong question. :-)
Take a look at this blog post:

Hi,
True, I was thinking only about the "Via" and "Record-Route" added by
Kamailio. Didn't know Record-Route had no short form (I was thinking of
something like "rr" due to rr module I guess). In this case I suppose
there
is not much to gain, only from "Via".
I'm facing some fragmentation issues. My goal is to make the SIP packet
as
small as possible while removing as less SIP headers as I can. I'd
still
like to use UDP.
Thanks,
Stefan

If smaller size is the target, then Via makes no big difference, so
it
was never a goal -- the changes in code should
not be big.
A quick option is to redefine MY_VIA in config.h to use the compact
form.
A proper option could be introducing a core parameter, adding a new
define for the short version and use the normal or short form a
matter
of the parameter value. The function that needs
to be changed is
via_builder().
Cheers,
Daniel

valid :-)

I can’t remember such a setting anywhere and am
curious on why it’s
needed.
