Administrator's Manual 1. Introduction
Version 2.2.8 19 400HD Series IP Phones
1 Introduction
This manual is intended for the system administrator responsible for setting up and
configuring the 420HD, 430HD, 440HD and 405 IP Phones.
AudioCodes' IP phones are based on AudioCodes' proprietary High Definition (HD) voice
technology, providing clarity and a rich audio experience in Voice-over-IP (VoIP) calls. The
phones are fully-featured telephones that provide voice communication over an IP network,
allowing you to place and receive phone calls, put calls on hold, transfer calls, make
conference calls, and so on.
The phone offers a wide variety of management and configuration tools:

Phone's LCD display user interface -easy-to-use, menu-driven display screen,
providing basic phone configuration and status capabilities

Web interface - provides a user-friendly Web interface that runs on a Web browser
(Microsoft®Internet Explorer is the recommended browser).

Configuration file -text-based file (created using any plain text editor such as
Microsoft's Notepad) containing configuration parameters and which is loaded to the
phone using the Web interface or a TFTP, FTP, HTTP or HTTPS server.

TR-069 for remote configuration and management

IP Phone Management Server (refer to IP Phone Management Server Administrators
Manual).
For a detailed description on hardware installation and for operating the phone's call
features, refer to the User's Manual.
