Megaco/H.248 is a protocol for control of elements in a + physically decomposed multimedia gateway, enabling separation of + call control from media conversion. A Media Gateway Controller + (MGC) controls one or more Media Gateways (MG).

+

This version of the stack supports version 1, 2 and 3 as + defined by:

+ + +

version 1 - RFC 3525 and H.248-IG (v10-v13)

+ + +

version 2 - draft-ietf-megaco-h248v2-04 & H.248.1 + v2 Corrigendum 1 (03/2004)

+ + +

version 3:

+ + +

prev3a - as defined by TD-33 (except segments)

+ + +

prev3b - TD-33 updated to be backward compatible with v2 + (except segments)

+ + +

prev3c - As defined by ITU H.248.1 (09/2005) + (except segments)

+ + +

v3 - Full version 3 as defined by ITU H.248.1 (09/2005) + (including segments)

+ + + + +

The semantics of the protocol has jointly been defined by two + standardization bodies:

+ + +

IETF - which calls the protocol Megaco

+ + +

ITU - which calls the protocol H.248

+ + + +
+ Scope and Purpose +

This manual describes the Megaco application, as a component + of the Erlang/Open Telecom Platform development environment. It + is assumed that the reader is familiar with the Erlang + Development Environment, which is described in a separate User's + Guide.

+
+ +
+ Prerequisites +

The following prerequisites is required for understanding the + material in the Megaco User's Guide:

+ + +

the basics of the Megaco/H.248 protocol

+ + +

the basics of the Abstract Syntax Notation One (ASN.1)

+ + +

familiarity with the Erlang system and Erlang programming

+ + +

The application requires Erlang/OTP release R10B or later.

+
+ +
+ About This Manual +

In addition to this introductory chapter, the Megaco User's + Guide contains the following chapters:

+ + +

Chapter 2: "Architecture" describes the architecture + and typical usage of the application.

+ + +

Chapter 3: "Internal form and its encodings" describes + the internal form of Megaco/H.248 messages and its various + encodings.

+ + +

Chapter 4: "Transport mechanisms" describes how + different mechanisms can be used to transport the + Megaco/H.248 messages.

+ + +

Chapter 5: "Debugging" describes tracing and debugging.

+ + +
+ +
