#
# This file specifies extra SIP headers not included in sip_t structure
#
# The parsed headers are accessed with function (or macro) like sip_refer_sub()
# e.g., sip_refer_sub_t *rsub = sip_refer_sub(sip);
#
# The line format is: 
# C-name @SINCE sip_t-like-comment
#
# Put all experimental things after EXPERIMENTAL HEADER LIST STARTS HERE...
