I am new to VoIP and think about getting started with Asterisk.
There’s just one open question left:
How are central phone books (One centrally managed phone directory for all hard phones in the whole Company) managed?
Does Asterisk provide such a feature?
If no which hard-phones do?
I am not aware of any thing like this available but I would think you could accomplish a phone book with a PHP page that parses your Asterisk config files. The polycom phones have a directory option but it is not perfect, updates require rebooting all of the phones.
