Introduction

This chapter provides an overview of ISoIP and H.323 gateways and describes the tasks involved in configur-
ing them.
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 con-
text. It handles connections between different technologies or protocols and contains general gateway configura-
tion parameters. In SmartWare there is an ISoIP and an H.323 gateway. The ISoIP and H.323 interfaces in the
CS context are implicitly bound to these gateways. The H.323 gateway must be bound explicitly to interfaces in
the IP context. The ISoIP gateway detects the correct IP interface on the IP context for its call automatically,
therefore no binding is needed.
one instance of each gateway. The name of the H.323 gateway is h323 and the one for the ISoIP gateway is isoip.
Gateway configuration task list
This chapter describes the configuration of the H.323 and ISoIP gateways. Some parameters could be config-
ured in the gateway configuration mode and overwritten in another configuration mode. For example the
default value for the voice codec for ISoIP connections is set in the gateway configuration mode and could be
overwritten in the ISoIP interface. All possible configurations which are involved in a specific configuration
