Workaround: Use the uncompressed WAV format.  This is good for about +10 dB
compared to the compressed formats, for some bizarre reason.  It's not just
voicemail, recordings made with Record() are affected, too.

There was a bug filed about this.  It was marked as a wontfix, as I recall,
because no one would step forward with code or $$$.
