Nothing in the format portions of asterisk should be doing anything to
volume. It would be fairly inappropriate for them to change the volume.

What you may need to do is use a program called normalize to bring the
volume of your mp3s up to the volume you are expecting, and then put
your modified files in the asterisk sounds dir. This will benefit from
only modifying the volume once, and not on every playback. If you get in
the habit of checking your files with normalize before deploying them,
you will have a consistent volume level.
