The quickest and easiest way to get this list would be to start with a  
nearly complete list of vars we set by routing a sip call to the info  
app and recording all the sip_* variables listed.  To get a list of  
vars we look for you can grep mod_sofia for  
switch_channel_get_variable.  Please note we use #defines for some of  
the var names, so if they are all caps without quotes you will need to  
find the define.  This should get you 95% of the way.
