The IESG has received a request from the Session Initiation Protocol Core
WG (sipcore) to consider the following document:
- 'Session Initiation Protocol (SIP) Response Code for Indication of
   Terminated Dialog'
  <draft-ietf-sipcore-199-05.txt> as a Proposed Standard

This is the second IETF last call for this document. The previous last call was on version -02.
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. A full summary
of the changes are available in section 13 of the document.

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the mailing lists by 2011-02-21. Exceptionally, comments may be
sent to instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.


   This specification defines a new Session Initiation Protocol (SIP)
   response code, 199 Early Dialog Terminated, that a SIP forking proxy
   and a User Agent Server (UAS) can use to indicate towards upstream
   SIP entities (including the User Agent Client (UAC)) that an early
   dialog has been terminated, before a final response is sent towards
   the SIP entities.
