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.
Note that the prerecorded tones are used only for generation of tones. Detection of tones is
performed according to the CPT file.
17.2.1 PRT File Format
The PRT dat file contains a set of prerecorded tones to be played by the Mediant 1000
during operation. Up to 40 tones (totaling approximately one minute) 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
file using the TrunkPack Downloadable Conversion utility (refer to Section
433).
The raw data files must be recorded with the following characteristics:
Coders:
Rate:
Resolution: 8-bit
Channels:
The generated PRT file can then be loaded to the Mediant 1000 using the BootP/TFTP
utility (refer to Section
5.8.2
on page 196).
