It would be good if we had a parser for incoming sip messages that 
strictly complied with the ABNF in RFC3261 & RFC2234. I have come
across http://www.nongnu.org/bnf/ that may be able to generate the 
code automatically (not tried). Any non-compliance to the ABNF 
should be responded to with a "400 Bad Request"
