9 years ago I'm going to close this for now.
Right now sngrep does not require to understand SIP protocol. If we implement some kind of validator, syntax checker, or payload analysis, osip2 parser functions will fit perfectly.
Sngrep sip parser using strings scan is fast but simple and not compliant with any RFC. Maybe using a library, like libosip[1] could be a nice addition, at the cost of adding an extra dependency.
