Prerecorded Tones (PRT) File
The Call Progress Tones mechanism has several limitations, such as a limited number of
predefined tones and a limited number of frequency integrations in one tone. To work around
these limitations and provide tone generation capability that is more flexible, the PRT file can
be used. If a specific prerecorded tone exists in the PRT file, it takes precedence over the
same tone that exists in the CPT file and is played instead of it.
The prerecorded tones are used only for generation of tones. Detection of tones
is performed according to the CPT file.
PRT File Format
The PRT
dat
file contains a set of prerecorded tones to be played by the gateway during
operation. Up to 40 tones (totaling approximately 10 minutes) can be stored in a single file in
flash memory. The prerecorded tones (raw data PCM or L8 files) are prepared offline using
standard recording utilities (such as CoolEdit
TM
) and combined into a single file using the
TrunkPack Downloadable Conversion utility (see
Creating a Loadable Prerecorded Tones
File
).
The raw data files must be recorded with the following characteristics:
Coders:
G.711 A-law, G.711 µ-law or Linear PCM
Rate:
8
kHz
Resolution:
8-bit
Channels:
mono
The generated PRT file can then be loaded to the gateway using the BootP/TFTP utility (see
Configuration Files Parameters
) or using the Embedded Web Server (see
Auxiliary Files
).
The prerecorded tones are played repeatedly. This enables you to record only part of the
tone and play it for the full duration. For example, if a tone has a cadence of 2 seconds on
and 4 seconds off, the recorded file should contain only these 6 seconds. The PRT module
repeatedly plays this cadence for the configured duration. Similarly, a continuous tone can
be played by repeating only part of it.
Voice Prompts File
The voice announcement file contains a set of Voice Prompts to be played by the gateway
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 gateway using the BootP/TFTP
utility (see
Configuration Files Parameters
) or using the Embedded Web Server (
Auxiliary
Files
).
