Chapter 2: Overview of Voice over IP (VoIP) and Network Protocols

Introduction

This chapter describes the differences between data and voice networks, and the factors that influence the performance of VoIP. The installation and administration of 4600 Series IP Telephones on Avaya Media Servers, and the installation and configuration of DHCP and TFTP are addressed.

Overview of Voice over IP (VoIP)

The 4600 Series IP Telephones allow enterprises to use Voice over IP (VoIP). VoIP uses packet-switched networks over the Public Switched Telephone Network (PSTN) instead of telephony. However, using data networks to transmit voice packets poses a problem. Data networks were not designed for the specific qualities required by voice traffic.

Data and Voice Network Similarities

Data and voice networks share similar functions because of the nature of networking.

●Signaling: establishes a connection between two endpoints.

In a voice network, signaling helps identify who the calling party is trying to call and where the called party is on the network. Traditional telephony uses terminals with fixed addresses. Traditional telephony establishes a fixed connection for the communication session between two such terminals, allocating fixed bandwidth resources for the duration of the call.

IP communications constitute a connectionless network, having neither fixed addresses nor fixed connections.
