You have to remove the hard drive from the Dispatch and install it into a PC, or you could also install it into a USB Hard Drive case. You'll need a software like Norton/Symantic Ghost. It only takes about 5 minutes to image the Dispatch Hard Drive.

Once you have the image, you can load it onto a new hard drive and install it into the Dispatch. You can then install the latest/greatest software from the Vodavi web site.

It would not be practible to do this with another customers voice mail.
