Technical Summary

   RFC4856 describes the annexa parameter for G723 and the annexb
   parameter for G729, G729D and G729E. However, the specification does
   not describe the offerer and answerer behavior when the value of the
   annexa or annexb parameter does not match in the Session Description
   protocol (SDP) offer and answer.  This document provides the offer/
   answer considerations for these parameters and updates RFC4856.


Working Group Summary

   There is WG consensus behind this draft. All issues raised during
   and before WGLC have been addressed.  


Document Quality

  This document clarifies behavior with the discussed SDP parameters
  to be in line with existing specifications and pragmatic
  implementations.  The document has been discussed in MMUSIC,
  PAYLOAD, and AVTEXT working groups and has been revised according to
  the feedback.
