Tranfering Voice Mail to an alternate medium

[Humble Pie]

My voicemail holds about 20 or 25 messages I think. Here's my dilema. I have a bunch of messages saved (like 15 or so) so often my mailbox fills up and my people leave me nasty text messages telling me to empty my box. The messages I have saved are truly classic; some are rambling drunken confessions from my buddies and dirty sexy messages from ex-girlfriends. My phone doesn't have a speaker-phone option so I can't really transfer the messages to an audio cassetee. My question is: is there a way to move my VM messages to another medium, like a voice data file or something and save them on my PC?
