Technical Summary

   This specification defines a new SIP response code, 199 Early Dialog
   Terminated, which a SIP forking proxy and a UAS can use to indicate
   upstream towards the UAC that an early dialog has been terminated,
   before a final response is sent towards the UAC

Working Group Summary

   There is consensus in the SIPCORE working group to publish this
   document despite early concerns about the utility of the mechanism. 
   There was significant discussion of the document on the
   working group mailing list, including many detail adjustments after
   publication request. While resolving review comments, an issue with the
   interaction of the 199 response and the 100rel extension was identified and 
   addressed by the SIPCORE working group.
