Mike,
I don't think unison is a workable solution. It doesn't scale. The network and
system load would increase exponentially as we added asterisk servers to our
cluster.

Subject: Re: [Asterisk-Users] Voicemail with NFS
I don't know how big your voicemail system is, but have you considered
using
Unison to syncronize the vm accross all your servers? I'm deploying
multiple
servers with two vm servers, each sync'ed every 5? minutes. If one
fails,
the other one should be "good enough."
Just a though,
Mike
