Dynamic Host Configuration Protocol (DHCP) is a standardized protocol that
enables clients to be dynamically assigned with various configuration parameters,
such as an IP Address, subnet mask, default gateway, and other critical network
configuration information. DHCP servers centrally manage such configuration data,
and are configured by network administrators with settings that are appropriate for a
given network environment. The handset will use the following DHCP options if

matches this behavior, using TFTP to receive its configuration information from the
CallManager. It can also use TFTP to update the handset software over the 802.11b
wireless LAN.
