This How-To covers converting music on hold/custom recordings into the correct format for the Avaya IP Office/ShoreTel systems, but can be applied to other systems if they support the same file settings or if you know the correct settings required.
1: Download Audacity
Download the free audio editor “Audacity” from the below link:
2: Open Music File In Audacity
3: Modify The Track Settings
Once you have opened the file, modify the following settings:
Project Rate (Hz): 8000
Tracks -> Stereo Track to Mono
4: Export Audio
All that’s left to do is to export your file. Go to File -> Export Audio (Ctrl + Shift + E) and you will see the export window appear asking you where you would like to save your file. Make sure you set the following settings when exporting:
Save as type: Other uncompressed files
Header: WAV (Microsoft)
Encoding: Signed 16 bit PCM
Once these settings have been confirmed, save the file.
All that’s left to do after conversion is copy the files to their relevant folders/locations.
For reference, the following audio settings are supported on Avaya/ShoreTel systems:
PCM/Uncompressed, 16-bit, 8 kHz, Mono
µ-law, 8-bit, 8 kHz, 16 kHz, Mono
α-law, 8-bit, 8 kHz, 16 kHz, Mono
16-bit, 8 kHz, Mono
16-bit, 16 kHz, Mono
All files must be in .WAV format. Files such as .mp3 are not supported.
