Chapter 1: Introduction

The Avaya G250 and Avaya G350 Media Gateways are high-performance converged telephony
and networking devices that are located in small branch locations, providing all infrastructure
needs in one box – telephone exchange and data networking. The G250 and G350 each
feature a VoIP engine, WAN router, and Power over Ethernet LAN switch. The G350 provides
full support for legacy DCP and analog telephones. The G250 supports legacy analog
telephones, and the G250-DCP model also supports DCP telephones.
The G350 is designed for use in a 16-40 user environment, but can support sites with up to 72
stations. The G250 is designed for smaller branch offices with two to eight users.
