[Asterisk-Users] Re: [Asterisk-biz] Case studies for Asterisk Voicemail

[Alistair Cunningham]

William,

I'm happy with the architecture options, as this is a company WAN with 
dedicated fibre links, and I'll be securing the database and NFS servers 
comprehensively.

All I need are case studies to assure the customer that they're not the 
first people to do this on Asterisk. Positive reports on either method 
are fine, as long as they're in the several thousand user range, and are 
for production systems.
