It depends on what software you use for MOH.  mpg123 is the default.

Check the switches used by mpg123 and see if there is an option to lower
the volume and then change it in musiconhold.conf.  If I understand it
correctly, the -g option is what you want.

I use madplay.  It has an option to lower the volume.
