Who I have the same questioned this topic

I am in the process of trying to do a full backup before doing a factory reset in the hopes of fixing some quirks that have been occurring on my Edge.  I have a few voicemails I moved from the active area to "Saved" but need to make sure those are backed up.  The Verizon Cloud does not show if these have been saved.

Does anyone know where on the phone these items are stored?  If I can locate the storage area I can download them to my PC or even move them to the SD card.  I've been through every possible folder I can locate but the voicemails aren't there.
