Introduction
This chapter provides an overview of the SIP 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.
A gateway connects two contexts of different types, For example, the CS and the IP context. It handles connec-
tions between different technologies or protocols and contains general gateway configuration parameters. The
SIP gateway is an implementation of a Session Initiation Protocol (SIP) User Agent according to RFC 3261.
The SIP gateway uses SIP CS interfaces, which are explained in detail in the chapter about SIP Interface Con-
figuration. The SIP interfaces in the CS context must be explicitly bound to a SIP gateway. The SIP gateway
itself must be bound explicitly to an IP interface in the IP context.
gateway. SmartWare supports multiple instances of the SIP gateway. The SIP gateway is enabled by default.

Gateway configuration task list
This chapter describes the configuration of the SIP gateway. Some parameters can be configured in the gateway
configuration mode and may be overwritten in another configuration mode, For example, in the SIP CS inter-
face. For example, the default VoIP profile to be used with the gateway is configured in the gateway configura-
tion mode. However it can be overwritten by another VoIP profile specified in the SIP CS interface. All
