Description:volgain can be used to increase the volume of voicemail messages sent over email, but it increases the volume uniformly across all messages so a loud message gets even louder.

The attached patch (against svn trunk) adds a "volheadroom" option that uses sox to normalize voicemail messages sent over email to leave only the specified amount of headroom. This should leave all voicemail messages very close to the same volume.

Our current configuration uses "volheadroom=-0.5".
