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.
