The VoiceMailMain() app can be told that the user has been 
pre-authenticated; this means you can use any application you like to 
authenticate the user, and the VM app won't prompt them for the mailbox 
number and PIN.

So.. you can build whatever dialplan functionality you wish to 
incorporate your biometric technology. If your system can be driven by a 
script (Perl/Python/Ruby/etc.) this could easily be done via the AGI 
mechanism.
