This section describes how to configure the basic network parameters that are required
for the IP phones to operate in the network.
DHCP (Dynamic Host Configuration Protocol) is a network protocol that is used to
dynamically allocate network parameters to hosts connected to a network. The
automatic distribution of network parameters to hosts eases the administrative burden
of maintaining IP networks. The IP phones comply with the DHCP specifications
documented in RFC 2131. If using DHCP, the IP phones connected to the network
become operational without having to be manually assigned IP addresses and
additional network parameters. By default, DHCP is enabled on the IP phones.
DHCP Option
DHCP provides a framework for passing network information to devices on a TCP/IP
network. Network and other control information are carried in tagged data items that
are stored in the options field of the DHCP message. The data items themselves are also
called options.
