Over research of SIP flow at media engine, I think SIP stack within media engine is derived from open source SIP stack GNU-oSIP. Right?
Because media engine and oSIP has same parsing flaw. I have developped SIP stack for several years for Radvision. In order to achieve high efficiency, parsing component shoudl be generated by Lex or Yacc or other commercial stuffs.

Nice try – not even close. The VOIP Media engine is proprietary and our own.

If you have a ready-made Lex/Yacc implementation (i.e. lexer and grammar files) of SIP parsing, we would love to see it. By all means, please share. :)
