Kamailio is a toolbox where you build your own application. These kind of headers are non-standard but easily parsed and handled in your Kamailio configuration.  There are very few headers of all possible headers out there that the source-code actually use. The rest is up to your configuration script, especially when it comes to variables prefixed with "x-", that are for internal non-standard use.
