      and grab the RFC  3261

 http://www.faqs.org/rfcs/rfc3261.html

  as well as the source in asterisk (1.4.11 here)

   "asterisk-1.4.11/channels/chan_sip.c"

 I would guess that reading the RFC and understanding the
 implementation in Asterisk will take you to places few others
 have been to...good luck !
