3Com VCX V7111 VoIP SIP Gateway User Manual 147C HAPTER 6: INI FILE C ONFIGURATION OFTHE VCX V7111As an alternative to configuring the VoIP gateway using the Web Interface (see Chapter 5:Configuring the VCX V7111 on page 43), it can be configured by loading the ini filecontaining Customer-configured parameters.The ini file is loaded via the BootP/TFTP utility (see Appendix B: The BootP/TFTPConfiguration Utility on page 209) or via any standard TFTP server. It can also be loadedthru the Web Interface (see Dynamic Jitter Buffer Operation on page 127).The ini file configuration parameters are stored in the VCX V7111 non-volatile memory afterthe file is loaded. When a parameter is missing from the ini file, a default value is assigned tothat parameter (according to the cmp file loaded on the VCX V7111) and stored in the non-volatile memory (thereby overriding the value previously defined for that parameter).Therefore, to restore the device’s default configuration parameters, use the ini file withoutany valid parameters or with a semicolon (;) preceding all lines in the file.Some of the VCX V7111 parameters are configurable through the ini file only (and not via theWeb). These parameters usually determine a low-level functionality and are seldom changedfor a specific application.For detailed explanation of each parameter, see Chapter 5: Configuring the VCXV7111 on page 43.Secured ini FileThe ini file contains sensitive information that is required for the functioning of the VCXV7111. It is loaded to, or retrieved from, the device via TFTP or HTTP. These protocols areunsecured and vulnerable to potential hackers. Therefore, an encoded ini file significantlyreduces these threats.You can choose to load an encoded ini file to the VCX V7111. When you load an encoded inifile, the retrieved ini file is also encoded. Use the ‘TrunkPack Downloadable ConversionUtility’ 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 loadingprocedure. For information on encoding / decoding an ini file see Encoding / Decoding an iniFile on page 236.Modifying an ini FileTo modify the ini file, follow these steps:1 Get the ini file from the gateway using the Embedded Web Server (see Dynamic JitterBuffer Operation on page 127).
