6 ini File Configuration of the Mediant 2000

As an alternative to configuring the VoIP gateway using the Web Interface (refer to Section 5 on page 39), it can be configured by loading the ini file containing Customer-configured parameters.

The ini file is loaded via the BootP/TFTP utility (refer to Appendix B on page 189) or via any

standard TFTP server. It can also be loaded through the Web Interface (refer to Section 5.9.5 on page 69).

The ini file configuration parameters are stored in the Mediant 2000 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 Mediant 2000) 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 Mediant 2000 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.

6.1Secured ini File

The ini file contains sensitive information that is required for the functioning of the Mediant 2000. 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 Mediant 2000. 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, refer to Section G.1.3 on page 217.

6.2Modifying an ini File

To modify the ini file, take these 3 steps:

1.Get the ini file from the gateway using the Embedded Web Server (refer to Section 5.9.5 on page 69).

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).

This method preserves the programming that already exists in the device, including special default values that were preconfigured when the unit was manufactured.

Tip: Before loading the ini file to the gateway, verify that the extension of the ini file saved on your PC is correct: Verify that the check box ‘Hide file extension for known file types’ (My computer>Tools>Folder Options>View) is unchecked. Then, confirm that the ini file name extension is xxx.ini and NOT erroneously xxx.ini.ini or xxx~.ini.
