I'm honestly dubious of the entire fixed dictionary approach. Now the LZW patent is expired (as of 2004), there's an extremely lightweight dynamic dictionary algorithm with almost no overhead available in addition to other successful alternatives (zlib/gzip). I expect most mobile devices to have zlib code for HTTP (and likely TLS) in order to save bandwidth anyway, why not allow them to reuse that code for SIP? Does the extra complexity of a custom fixed-dictionary algorithm with negotiated dictionaries provide sufficient real benefits over the general purpose likely-already-present compression code?

To the extent that I can evaluate this document it seems fine. However that wasn't really enough that I felt comfortable balloting a no-obj. sigcomp is one of those things I have not spent the time to understand.
