What they actually asked for was both a copy of the SIP grammar
and any lex/yacc version. Good luck to anyone who develops
a parser without looking at the definitive grammar definition.
In fact by studying the SIP spec you may learn that lex/yacc
is not the best way to go.

All I can recall is the postings on an antlr based SIP/SDP
message parser. See:
