Summary:  As ready as possible


The writeup says "It was difficult to get adequate reviews of this document."
I'd say that goes for this whole class of documents. Reviewing the details of SIP
call flows is not for ordinary mortals. I have not checked the call flows, and I think
we have to trust the WG on this. But our experience (those in RFC4244 being buggy, for
example), makes me wonder about the wisdom of publishing such documents at all under
the RFC "brand". Maybe they should just be put on a wiki somewhere, and fixed as bugs
are found.

The small amount of narrative text is well written.

For the record, I ballotted 'No Objection' on RFC4244 in 2005.
