Many (maybe most) SIP stacks use some kind of ABNF compiler to help with encoding and decoding of messages, and I think the suggestions for ANTLR especially is appropriate (there are tools much older than ANTLR also).
Please understand, however, that the ABNF is not a COMPLETE description of the message encoding and decoding. The text explains that there are many cases where the ABNF as written will permit things that are not legal SIP, and there are cases where the ABNF is not quite consistent or complete. We made a major effort in 3261 to get as complete and consistent ABNF as we could, but sometimes clarity is more important that completeness and consistency. I also call your attention to the bugzilla list: http://bugs.sipit.net/reports.cgi where you can find several reported errors in the ABNF.
