asterisk users - Aug 2006 - SIP_HEADER function; what names are available?

I have read the wiki about the SIP_HEADER function 
(http://www.voip-info.org/wiki/index.php?page=Asterisk+func+sip_header). 
Where can I get a list of the names that are available to be used with the 
function e.g. TO is one name as in ${SIP_HEADER(TO)}. What are the others?

Regards

Cameron

I would guess that you can check the RFC. Easier is to turn on SIP  
debug and see the INVITE packet yourself and
check the headers that you have with your equipment.
