Hey Eric,
Not at all. And that is a very good point. I would be interested to see 
how the program handles voicemail files. Unfortunately, I wouldn't be 
able to get to it anytime soon (within two weeks or so), but if anyone 
is interested in seeing the results, email me off list and i'll see what 
test i can pull together, otherwise i'll put this on my "project-ideas" 
list and get to it whenever.
