The SV9100 networking manual has info on how to setup auto config up with ipphonemanager and dhcp, ftp server according to doc u need
 IP Phone Manager and software to create the config file for the IP terminals.
Software is available for download free on the NEC website.
 FTP server and free software available on the web.
 DHCP Server supporting ability to define the following:
 Vendor Class
 Option Codes

I havent done one from scratch but did a relocation with a different ip range on a vlan and creating a new config file was pretty easy.
