Voice Prompts File; Cas Protocol Configuration Files - 3Com VCX V7122 User Manual

Voice Prompts File

The Voice Prompts file is applicable only to the VXML application.
The voice announcement file contains a set of Voice Prompts to be played by the VCX
V7122 during operation. The voice announcements are prepared offline using standard
recording utilities and combined into a single file using the TrunkPack Downloadable
Conversion Utility.
The generated announcement file can then be loaded to the VCX V7122 using the
BootP/TFTP utility (see
Web Server (see Auxiliary Files
If the size of the combined Voice Prompts file is less than 1 MB, it can permanently be stored
in flash memory. Larger files, up to 10 MB, are stored in RAM, and should be loaded again
(using BootP/TFTP utility) after the VCX V7122 is reset.
The Voice Prompts integrated file is a collection of raw voice recordings and / or wav files.
These recordings can be prepared using standard utilities, such as CoolEdit, Goldwave and
others. The raw voice recordings must be sampled at 8000 kHz / mono / 8 bit. The wav files
must be recorded with G.711µ-Law/A-Law/Linear.
When the list of recorded files is converted to a single voiceprompts.dat file, every Voice
Prompt is tagged with an ID number, starting with "1". This ID is used later by the VCX
V7122 to start playing the correct announcement. Up to 1000 Voice Prompts can be used.
The Voice Prompt ID is used in the VoiceXML file to specify the message that is to
be played.
3Com provides a professionally recorded English (U.S.) Voice Prompts file.
