Function 6: Recording
Function 633: MOH volume
If a custom MOH is recorded, the output volume can be adjusted in this function.
Range: 1 (faint)–12 (loudest).
Default: 6.
• If an external audio source such as a radio is used for MOH, adjust the volume at the source.
• If an internal source is used but callers cannot dial off hold, lower the MOH volume.
• To turn live MOH volume completely off, turn off volume at the source.
• To turn recorded MOH volume completely off, use Function 631 to select one of the prompts in
the range of 594–598, but make sure it's blank. These prompts are blank by default; if you have
recorded some audio on all of them, just select one and record a few seconds of silence.
