I'm currently dealing with SIP messages at work. My manager actually told me not to be so pedantic with the parsing as we got some complaints from other vendors (and privately, I thought: why bother with standards if you aren't going to follow them?) I ended up with logging a warning instead of returning an error. Sigh.

You can't actually parse SIP messages unambiguously these days. Even big open source projects like Asterisk and OpenSIPS have strictly different and incompatible interpretations. I'm purely talking about parsing, not actually interpretation of the content. It's that bad. And yes, this opens up security holes when one system is trusted to read the message correctly.
