Since lots of information is stored in the set itself what happens when you replace a phone, will the VOIP server back up the phones data?
You can set the phone to retrieve it's configuration from the server. Then you configure the phone settings on the server, which gives them to the phone when it boots up.
You could also configure the settings directly on the phone, but you will probably find this unmanageable for more than a few phones, and there will be no backup of the configuration settings.
