The WAV codec used in this instance is gsm (compressed).  Some .wav 
players assume that all .wav files are pcm encoded.

eg: Vonage sends me:

05-11-2004-19-43-.wav: RIFF (little-endian) data, WAVE audio, Microsoft 
PCM, 16 bit, mono 8000 Hz

But asterisk sends me:

msg0000.wav:   RIFF (little-endian) data, WAVE audio, GSM 6.10, mono 
8000 Hz

I haven't looked at the voicemail.conf settings to see if this is 
configurable.  I know that inside the voicemail spool area the raw pcm 
files were still there for me.
