PBXPlus Manual: Music File Format
Music File Format
We have found that music files work best in both MOH and Prompt applications when formatted as:
Wave (".wav"), PCM-Signed, 8-bit, 8khz mono OR Non-variable bitrate mp3
Music File Volume
There are no tools in the PBX to adjust MOH volume. If the customer needs louder/quieter MOH, it is advised to use software like Audacity or Wavepad to adjust and save the file at the new level, and load that file into the PBX.
