Introduction

SmartWare Software Configuration Guide 

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. 

 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 
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.
