Can't say - but I do notice a significant difference between just the linear (wav) and gsm compressed (WAV) files you provided... I just checked a voicemail off of my system (CVS-v1-0-11/03/04) and I notice I'm getting the same effect, though I'd not realised it before. Although my attenuation seems less severe than yours you can really visualise the drop in energy levels by putting the different files through Sonogram (http://www.dfki.de/~clauer/programming.html)
Can you publish the 'format=' line from /etc/asterisk/voicemail.conf off of your server? Simply placing 'wav' as the first format in the list may be enough to work around the problem for now - though it will cause attachment size issues for people getting their VMs via email.
