38 • H.323 gateway configuration

Introduction

This chapter provides an overview of the H.323 gateway and describes the tasks involved in its configuration.
When communication is required between different networks a gateway is always needed between them. A
gateway provides:
• Data format translation, e.g. audio and video CODEC translation
• Control signaling translation, e.g. call setup and termination functionality on both sides of a network.
In the case of SmartWare, a gateway connects two contexts of different types, For example, the CS and the IP
context. It handles connections between different technologies or protocols and contains general gateway con-
figuration parameters. In SmartWare one of these gateways is the H.323 gateway. This is an implementation of
the ITU-T H.323 Version 4 standard. The H.323 uses H.323 CS interfaces, which are explained in detail in
the chapter about H.323 Interface Configuration. The H.323 interfaces in the CS context must be explicitly
bound to a H.323 gateway instance. The H.323 gateway itself must be bound explicitly to an IP interface in
the IP context. Figure 77
instance of the H.323 gateway. The default name of the H.323 gateway is h323.
Gateway configuration task list
This chapter describes the configuration of the H.323 gateway. Some parameters can be configured in the gate-
way configuration mode and may be overwritten in another configuration mode, For example, in the H.323
CS interface. For example, the default VoIP profile to be used with the gateway is configured in the gateway
configuration mode. However it can be overwritten by another VoIP profile specified in the H.323 CS inter-
