The business I am working with has a standard phone system (not VOIP).
We want to set up a phone so that customers can call in and record
their testimonials. We then want to transfer those voice mails to the
PC so we can edit the testimonials, make podcasts etc. My issue is,
how to get the voice mail from the phone to the PC?

Basically, we want to play back the messages and have them record to
the PC... You can assume the PC has a modem on it, however, we need to
use our standard phone system to take the call and record the message.
