Summary: This draft specifies a SIP response code for the callee to indicate

Major issues: None

Minor issues: None

Nits/editorial comments:

Page 4, 1st full paragraph, 2nd sentence: I can't parse this sentence as
written.  It appears to be a list, but then has a clause (starting at "based
on") that doesn't fit neatly in the sequence.  Perhaps inserting "and" before
"based" would help.  Append "as" after "well".

Page 5, Section 6, 2nd paragraph, 1st sentence: change "extract" to "exact".
