Just curious, but using NFS like that, do you allow your main call servers 
handle voicemail or do you have a specific voicemail box for that?  My 
boss's view on voicemail is that it's not mission critical for the phone 
system, we're mainly concerned about the level of uncertainty.  It's 
better to have the phone system up and capable of dialing 911 with no 
voicemail, than lose the voicemail and risk losing actual call volume, 
plus the more HA the non-critical parts get, the more it costs.
