I am planning to start using asterisk in our company, which have about 30 small offices. But I have some fundamental questions about planning and deploy.
My opinion about it: use one central asterisk server with user’s data in database + self-written web-interface. Each office will be connected to central office via tunnel.
So my question, is this solution appropriate? Or maybe I need addition asterisk server in each office? I need some help in this area: web link or some words.
