Getting Familiar with Configuration Concepts and
Terminology
Before using your device, it is recommended that you familiarize yourself with the basic
configuration concepts and terminology. An understanding of the basic concepts and terminology
will help you configure and manage your device more effectively and easily.
SBC Application
The objective of your configuration is to enable the device to forward calls between telephony
endpoints in the SIP-based Voice-over-IP (VoIP) network. The endpoints (SIP entities) can be
servers such as SIP proxy servers and IP PBXs, or end users such as IP phones. In the SIP world,
the endpoints are referred to as SIP user agents (UA). The UA that initiates the call is referred to as
the user agent client (UAC); the UA that accepts the call is referred to as the user-agent server
(UAS).
The following table describes the main configuration concepts and terminology.

Description
IP Group The IP Group is a logical representation of the SIP entity (UA) with which the
device receives and sends calls. The SIP entity can be a server (e.g., IP
PBX or SIP Trunk) or it can be a group of users (e.g., LAN IP phones). For
servers, the IP Group is typically used to define the address of the entity (by
its associated Proxy Set). IP Groups are used in IP-to-IP routing rules to
denote the source and destination of the call.
