Hi,
 
You wouldn't send a 199 unless you have already sent a non-100 1xx response, so 
the early dialog has already been created.
 
Regards,
 
Christer

Hi,


one questions on this draft.


Since RFC3261 says, non-100 1xx response for INVITE cause early-dialog creation.
does this draft will normativly change the criteria, excluding 199?


If, the answer is Yes, I think it need be stated explicitly in the draft.



thanks


Regards,
-Rockson

This draft is a work item of the Session Initiation Protocol Working Group of 
the IETF.


Title : Response Code for Indication of Terminated Dialog
Author(s) : C. Holmberg
Filename : draft-ietf-sip-199-00.txt
Pages : 9
Date : 2008-5-15
This specification defines a new SIP response code, 199 Early Dialog
   Terminated, which a SIP entity can use to indicate upstream that an
   early dialog has been terminated.  The response code can be used by a
   SIP entity, normally a forking SIP proxy, to allow the UAC to know
   that an early dialog has been terminated before it a final response
   is sent to the request.
