To my knowledge there is no direct implementation to do this.  The
workarounds that I'm aware of:

1. On the central Asterisk box that is storing your voicemails, make the
voicemail spool accessible via nfs (or samba, or whatever), mount the spool
directory on the remote asterisk box, and point astspooldir (in
asterisk.conf) to where you mounted the nfs share.  The remote asterisk
server then sees the voicemail files as they are written, but it doesn't
actually have to transfer them, so it's fairly quick.  This, of course,
would be foolhardy to do without a VPN connection.  I used this method on a
couple of servers for a while.  It's a bit hackish, but it works.

2. Store your voicemails in a database using odbc to connect (on both
asterisk machines).  Replicate the database from one machine to another.  Of
course, this would also be smart to do with a VPN tunnel.  I won't tell you
this is easy to set up (cause it ain't), but it's definitely a more elegant
solution than option 1.
