I'm sure that works well when the machines are together on one network. 
  What happens, though, when the machines are in geographically 
disparate locations, your voicemail volume is quite large, and you 
don't have ultra-high bandwidth links between them?  I haven't tried 
it, but I imagine the performance of the voicemail app wouldn't be so 
good on the remote servers.
