It's the default:
wav49|gsm|wav
Steve brought up the IP issue...what about .ogg? I am thinking, although this really doesn't address the issue of the audio levels, of a format that is not so "dead" as MS-GSM (yeah, it's kinda easy enough to pack GSM into MS-GSM, but the only mention of it ever within the IETF was the MS I-D). From what I recall, WMP will play .ogg (but I have not verified this).
But I digress....

p.s. this is from the -r v1-0 branch of CVS.

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.
Thanks.

Just out of curiosity...was the GSM codec in Asterisk ever verified against the ETSI reference inputs/outputs?

Any chance you could record a sample problem voicemail and
post all three
recorded formats (raw, wav and wav49) for download somewhere?
