provisions of Section 10 of RFC2026
Internet-Drafts are working documents of the Internet Engineering Task
Force (IETF), its areas, and its working groups. Note that other groups
may also distribute working documents as Internet-Drafts.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet- Drafts as reference material

Internet draft MEGACO Protocol July 30, 1999
Abstract
MEGACO/Recommendation H.248 defines the protocols used between elements
of a physically decomposed multimedia gateway. There are no functional
differences from a system view between a decomposed gateway, with dis-
tributed sub-components potentially on more than one physical devices,
and a monolithic gateway.
This document does not define how gateways, multipoint control units or
integrated voice response units (IVRs) work. Instead it creates a gen-
eral framework that is suitable for these applications.
Packet network interfaces may include IP, ATM or possibly others. The
interfaces will support a variety of SCN signalling systems, including
tone signalling, ISDN, ISUP, QSIG, and GSM. National variants of these
signaling systems will be supported where applicable.
