Administrator's Manual 1. Introduction
Version 3.4.3 17 400HD Series IP Phones
1 Introduction
This Administrator’s Manual is intended for network administrators responsible for
configuring AudioCodes’ IP phones in their enterprise telephony networks.
The manual covers AudioCodes’ low-end and high-end phone models:
Low-end phone models: 405HD, 430HD and 440HD
High-end phone models: 445HD, 450HD, C450HD and the HRS conference device
Note:
•Release Notes version 3.4.3 documents support only the following high-end phone
models:
√445HD
√450HD
√C450HD
√HRS conference device
•This Administrator’s Manual documents support both these and the following low-
end phone models:
√405HD
√430HD
√440HD
•When a feature is documented but support is still pending, a note will indicate this.
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.
For a detailed description on hardware installation and for operating the phone's call features,
see the phone’s User's Manual.

Administrator's Manual 2. Configuration Methods
Version 3.4.3 19 400HD Series IP Phones
2 Configuration Methods
The phones feature four optional configuration methods:
Configuration file. Text-based file, created using a text editor such as Microsoft's
Notepad. Contains configuration parameters. Loaded to the phone using provisioning
methods TFTP, FTP, HTTP/HTTPS. See Section 2.2 for more information.
Device Manager Pro/Express. See Section 2.3 for more information.
Phone screen. Easy-to-use, menu-driven screen providing basic phone configuration
and status capabilities. See the next section for more information.
2.1 Phone Screen
The Liquid Crystal Display (LCD) phone screen allows configuring phone Settings, Keys and
Administration menus.
2.1.1 Administration Menu
Note:
•The phone is password protected. The default password is 1234. To change the
login password, use the phone's configuration file.
•After entering the password, the access session is applied to all the submenus.
•To change the Administration screen's login password, use the configuration file.
To access the Administration screen:
1. Press the MENU key on the phone and navigate down to Administration.
Note: Alternatively, after pressing the MENU key you can press an item's number to
navigate to the item, for example, press 6 to navigate to Administration.
2. Press Select; you're prompted for a password.
3. Enter the administration password (Default: 1234) and then press the OK softkey.
2.1.2 Configuring the Web Interface's Port
If the network administrator requires the Web interface for a configuration purpose, they need
to assign it a port number.
To configure the Web interface port:
•Use the table as reference.
Table 2-1: Port Parameters
Parameter Description
system/http_server_port Assigns a port number to the Web interface.
The HTTP server by default uses port number 80. Range: 0-65535.
system/https_server_port Assigns a port number to the Web interface.
The HTTPS server by default uses port number 443. Range: 0-65535.

Administrator's Manual 20 Document #: LTRT-11973
2.1.3 Configuring User Login Credentials
The network administrator can configure the phone user's name and password.
To configure user's name and password:
•Use the table as reference.
Table 2-2: User Name and Password Parameters
Parameter Description
system/web_user_name The phone user name. Default: admin.
Applies only to the Web interface.
system/web_user_password The encrypted phone password. Default: 1234.
Applies only to the Web interface, and phone screen.
2.2 Configuration File
This section describes the configuration file and the parameters you can configure in it. The
configuration file can be loaded to the phone using automatic provisioning or from the Device
Manager. The subsections below describe configuration file syntax and linking additional
configuration files to a configuration file.
2.2.1 File Syntax
The configuration file can be created using a standard ASCII, text-based program such as
Notepad. The configuration file is a .cfg file with the file name being the phone's MAC
address: <phone's MAC address>.cfg.
The syntax of the configuration file is as follows:
<parameter name>=<value>
Make sure the configuration file conforms to these guidelines:
No spaces on either side of the equals (=) sign.
Each parameter must be on a new line.
Below is an example of part of a configuration file:
system/type=440HD
voip/line/0/enabled=1
voip/line/0/id=1234
voip/line/0/description=440HD
voip/line/0/auth_name=1234
voip/line/0/auth_password=4321
2.2.2 Linking Multiple Files
The Configuration file allows you to include links (URL and/or file name) to other
Configuration files that provide additional parameter settings. This is especially useful in
deployments with multiple phones, where the phones share common configuration but where
each phone has some unique settings. In such a scenario, a phone's Configuration file can
include unique parameter settings as well as links to additional Configuration files with
settings common to all phones.
Linking additional files is achieved by using the include function in the phone's Configuration
file. For example, the below Configuration file provides links to additional Configuration files
(shown in bolded font):
system/type=440HD
