It sounds as if the IMAP server is probably M$ Exchange.  If so,
perhaps you can set up a server-side rule to move voicemail into
a folder, instead of having it land in the inbox for fetchmail to
trip over.  You "should" be able to establish such a rule for your
own account without needing admin access -- although you may have
to find a Windoze box and fire up Outlook :(
