SmartWare Software Configuration Guide 47 • VoIP profile configuration

Introduction

This chapter gives an overview of VoIP profiles, and describes how they are used and the tasks involved in VoIP profile configuration.

A VoIP profile is a container for all datapath-related settings on VoIP connections. The profile settings apply to all calls going through the interface. A VoIP profile can be assigned to VoIP gateways and VoIP interfaces in context CS. If no profile is specified for a particular interface, a profile from the gateway the interface binds to is used instead. Figure 1 illustrates the relations between VoIP profiles, gateways and CS interfaces. The follow- ing components are configurable:

•Codecs and codec parameters (such as silence suppression, RTP payload type, and audio filters)

•DTMF relay

•Dejitter buffer

•Fax transmission

•Modem transmission

Configuring voice datapath options can improve or degrade the quality of the transmitted voice data. Many of the default val-

ues of these components have configured defaults that should only IMPORTANT be changed if required. Misconfiguration can strongly affect the

voice quality perceived by the user and the bandwidth require- ments of VoIP connections. Be sure you understand the meaning and impact of all commands prior to changing any settings.
