[Asterisk-biz] Case studies for Asterisk Voicemail

[Alistair Cunningham]

Race,

This is exactly what I had in mind. The database and NFS server will be 
shared between the Asterisks at each site, and every user will be 
visible from everywhere. I wouldn't plan to synchronise messages between 
remote servers - I've done it for VPIM audio names in the past, and it's 
not pleasant.

I have the architecture sorted out. All I need are case studies to 
assure the customer that they're not the first people to use this method.
