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                June 25, 1999

MEGACO/Recommendation H.GCP 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 RFC/recommendation does not define how gateways, multipoint control
units or integrated voice response units (IVRs) work.  Instead it
creates a general 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.
