Changing to analog would not preclude this from happening - voicemail security has no relationship to type of trunk. Granted, the calls to Cuba would be higher quality on digital trunk, but it could certainly still happen with analog. If the site doesn't dial international, first step is to simply have carrier block all international calling. You're still vulnerable to calls to countries within the NANP (Carribean island nations) - but they're not quite as wicked. You could have carrier block calls to those area codes.
