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

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.
