 This how-to describes the procedure for preparing a sound file for Music on hold. There are two ways depending on the operating system you are using:
  1) If you are using Linux, this is the command to convert MP3 files:        lame -b 16 -m m       --resample 8 --noshort        input-file.mp3 output-file.mp3    Please note: --noshort is a VERY IMPORTANT OPTION.      The size of the file will be greatly reduced: 10M MP3 will be around  700K.   2) If you are using Windows, this is the procedure:
 - Download RazorLame from:        http://www.dors.de/razorlame/index.php        - Download LAME binary from here and put LAME.exe in RazorLame  installation folder:        http://www.rarewares.org/mp3-lame-bundle.php        - Open RazorLame and drag-n-drop MP3 file      - Click on LAME button and select 'Load options'.        Find the 'presets' directory and select '01 Phone.rlo' preset.      - Change the Output directory on the first tab      - Press OK.      - Press 'Encode'      - Upload the encoded MP3 file and check the quality          Please note:      WinLAME doesn't work.
