Abstract

   This document is common text with Recommendation H.248 as
   redetermined in Geneva, February 2000.  It must be read in
   conjunction with the Megaco Errata, RFC 2886.  A merged document
   presenting the Megaco protocol with the Errata incorporated will be
   available shortly.

   The protocol presented in this document meets the requirements for a
   media gateway control protocol as presented in RFC 2805.
