Summary: Almost ready
--------

Minor issue:
------------

The acronym AOR is used 63 times in the draft without being defined, except by
implication
in the title of reference [18]. This, and the rather abrupt start to the
Introduction,
makes this a document that is quite hard to get into for an outsider. I know
what "SIP"
stands for, but it should be expanded in the Abstract, and I'd like to see at
least one
sentence of introduction to SIP before "One of SIP's primary functions is...".

Similarly, in the Introduction:

   Although the use of REGISTER requests to update reachability
      information for multiple users simultaneously is somewhat beyond the
         original semantics defined for REGISTER requests, ...

	 I deduce that REGISTER is a SIP message. But this isn't stated, and
	 I'd have expected
	 a reference to [4], where REGISTER is defined. Again, this is written
	 as an insider
	 document.

	 Once we get past the Introduction the draft seems very thorough and
	 clear,
	 and I (not being a SIP expert) could detect no technical issues.
