7.2 Updating the Auxiliary Files
The auxiliary files are configuration dat files that are loaded to the gateway (in addition to the ini
file) to enable enhanced gateway provisioning. The following auxiliary files are available:
coefficient, Voice Prompts, Call Progress Tones (CPT) and Prerecorded Tones (PRT). The Voice
Prompts file is currently applicable only to MGCP. Table
7-1 presents a brief description of the ini
file and of each auxiliary file.
Table 7-1: ini and Auxiliary Files Descriptions
File Type Description
Ini
Load the file to provision the MP-1xx parameters. The Embedded Web Server
enables practically full device provisioning but customers may occasionally require
new feature configuration parameters in which case this file is loaded.
Note that loading the ini file only provisions parameters that are contained in the ini
file. If a parameter is not specified in the ini file, values associated with that parameter
are reset to a default value. These values may not be the same as the values that
were configured for the VoIP gateway at the time of manufacture.
Note: After the file has completed loading, the VoIP gateway automatically restarts
(software is loaded from the flash).
Coefficient This file (different file for FXS and FXO gateways) contains the telephony interface
configuration information for the VoIP gateway. This information includes telephony
interface characteristics, such as DC and AC impedance, feeding current and ringing
voltage. This file is specific to the type of telephony interface that the VoIP gateway
supports. In most cases you have to load this type of file.
Voice Prompts The voice announcement file contains a set of Voice Prompts to be played by the
MP-1xx during operation on Call Agent request. Only MGCP is supported.
Call Progress
Tones
This is a region-specific, telephone exchange-dependent file that contains the Call
Progress Tones levels and frequencies that the VoIP gateway uses. The default CPT
file is: U.S.A.
Prerecorded
Tones
The dat PRT file enhances the gateway’s capabilities of playing a wide range of
telephone exchange tones that cannot be defined in the Call Progress Tones file.
¾ To load an auxiliary file via the Embedded Web Server, take these 6
steps:
1. Open the ‘Auxiliary Files’ screen (Software Update menu > Load Auxiliary Files); the
‘Auxiliary Files’ screen is displayed (shown in Figure
7-8).
2. Click the Browse button that is in the field for the type of file you want to load.
3. Navigate to the folder that contains the file you want to load.
4. Click the file and click the Open button; the name and path of the file appear in the field next
to the Browse button.
5. Click the Send File button adjacent to the field that contains the name of the file you want to
load. An asterisk in the screen section indicates that the file’s loading takes effect on-the-fly
(e.g., Voice Prompts file).
6. Repeat steps 2 to 5 for each file you want to load.
