1.  Introduction

   Since the initial development of H.248/MEGACO, a number of
   organizations have made use of the H.248/MEGACO protocol Package
   mechanism in order to allow a certain function to be controlled by
   H.248/MEGACO.  The H.248/MEGACO Package mechanism was introduced, in
   part, to allow organizations who had an in-depth knowledge in a
   particular functional area to independently produce a Package on this
   functionality.  This acknowledged the fact that neither the IETF
   MEGACO Working Group nor the ITU-T Study Group 16 possessed in-depth
   knowledge in all areas.  Whilst this approach has been successful in
   the number and range of Packages produced, in some cases these
   Packages were/are not fully aligned with H.248/MEGACO principles.
   Once a Package has been published and registered, it is problematic
   to rectify any issues.

   The introduction of problems/inconsistencies was caused, in part, by
   the fact that the Packages were not fully reviewed by H.248/MEGACO
   experts.  In fact, the IANA H.248/MEGACO registration process did not
   actually specify that an in-depth review should take place.

   The current H.248/MEGACO Package registration process was defined
   when the ITU-T Study Group 16 and the IETF MEGACO Working Groups were
   both active in H.248/MEGACO standardization and produced nearly all
   the registered Packages.  Packages were reviewed in the IETF MEGACO
   Working Group and the Working Group chair was the IESG-appointed

   expert in charge of the review of the requests for H.248 Package
   registration.  This meant that H.248 Packages underwent an informal
   review before being registered.  However, this has changed.

   The current situation is that now the IETF MEGACO Working Group is
   disbanded and new H.248/MEGACO development typically occurs through
   Question 3 of ITU-T Study Group 16 (notwithstanding email discussion
   on the IETF MEGACO mailing list).  This move to ITU-T-defined
   Recommendations is discussed in [RFC5125].
