The recommended installation method for IP phones uses a DHCP server. This section outlines by example, the basic steps for using a Windows server as the DHCP server for IP phone installation. The principles of defining a scope are applicable to most DHCP servers.

You will need the following information from the customer's network manager:

• The IP address range and subnet mask the IP phones should use

• The IP Gateway address

• The DNS domain name, DNS server address and the WINS server address

• The DHCP lease time

• The IP address of the IP Office unit

• The IP address of the PC running Manager (this PC acts as a file server for the IP phones during installation)
