1.3 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.
1.3.1 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.

Configuration Terms 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.
Proxy Set The Proxy Set defines the actual address (IP address or FQDN) of SIP
entities that are servers (e.g., IP PBX). As the IP Group represents the
SIP entity, to associate an address with the SIP entity, the Proxy Set is
