THE
As an alternative to configuring the VoIP gateway using the Web Interface (see
Web Management on page 41), it can be configured by loading the ini file containing
Customer-configured parameters.
The ini file is loaded via the BootP/TFTP utility (see
Configuration Utility on page 193) or via any standard TFTP server. It can also be loaded
through the Web Interface (see
page 72).
The ini file configuration parameters are stored in the VCX V7122 non-volatile memory after
the file is loaded. When a parameter is missing from the ini file, a default value is assigned to
that parameter (according to the cmp file loaded on the VCX V7122) and stored in the non-
volatile memory (thereby overriding the value previously defined for that parameter).
Therefore, to restore the default configuration parameters, use the ini file without any valid
parameters or with a semicolon (;) preceding all lines in the file.
Some of the VCX V7122 parameters are configurable through the ini file only (and not via the
Web). These parameters usually determine a low-level functionality and are seldom changed
for a specific application.

Secured ini File

The ini file contains sensitive information that is required for the functioning of the VCX
V7122. It is loaded to, or retrieved from, the device via TFTP or HTTP. These protocols are
unsecured and vulnerable to potential hackers. Therefore an encoded ini file significantly
reduces these threats.
You can choose to load an encoded ini file to the VCX V7122. When you load an encoded ini
file, the retrieved ini file is also encoded. Use the 'TrunkPack Downloadable Conversion
Utility' to encode or decode the ini file before you load it to, or retrieve it from, the device.
Note that the encoded ini file's loading procedure is identical to the regular ini file's loading
procedure. For information on encoding / decoding an ini file see
File on page 223.

Modifying an ini File

To modify the ini file, follow these steps:
1 Get the ini file from the gateway using the Embedded Web Server (see
Backing Up the Gateway Configuration
2
Open the file (the file opens in Notepad or a Customer-defined text file editor) and modify
the ini file parameters according to your requirements. Save and close the file.
3
Load the modified ini file to the gateway (using either the BootP/TFTP utility or the
Embedded Web Server).
