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.
Notes: If an external audio source such as a radio is used for MOH, adjust the volume at the source.
To turn live MOH volume completely off, turn off volume at the source.
To turn recorded MOH volume completely off, select (in Function 631) 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.
