I wonder if you have for example 100 IP-phones in your company connected to the Asterisk, can you have a Contact database of all the employees name and numer in the Asterisk and download this to the phones, so you only need to administrate all name and number at one place ?
What feature do you need from the IP-phones to require this function ? XML ?
Can you separate the central contactdatabase from every employees own number that they have in the phone, for examples number to family, friends, other businesspartners and so on. I mean if you update the central contact database, you don’t wont to lose these numbers.
Is there any solution on this problem ?
