I'm sure it has been covered, but flash would not make a good long term
voicemail option. Flash has a specific amount of times blocks can be
written to. My company has some hand held recorders in the hands of
doctors doing patient dictation, they are starting to see memory
failures after a little more than a year or so of use. This is due
partly because of the size of files. Each file will span multiple
blocks, and therefore increases the likelyhood you will come back and
write on the block again soon. A large card would stave off the problem
by allowing the least used method a bit longer before reusing the blocks
again.

All in all, you would probably be better off for storing the voicemail
in a CFII+ hard drive that doesn't add much to power, weight, heat, nor
noise all while reducing the chance of burning through the flash.
