Fetching Your Voicemail from the PC?

Ben Jackson asks: "I subscribe to the phone company's voicemail offering because it can take messages even when the line is busy. Although I would prefer vgetty, I can't afford to have several lines and a hunt group just to avoid missing calls. What I'm looking for is a tool you could call `fetchvmail' -- it would use a voice modem to retrieve voicemail and forward it on as a MIME attachment. Does anything like this exist?" We already have mgetty-voice and its ilk, why not something like this? Since many phone companies are now providing voice mail with the service, this would be a very useful utility indeed.
