DHCP Option
DHCP provides a framework for passing information to TCP/IP network devices. 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.
DHCP can be initiated by simply connecting the IP phone with the network. IP phones broadcast
DISCOVER messages to request the network information carried in DHCP options, and the
DHCP server responds with specific values in corresponding options.
The following table lists common DHCP options supported by IP phones.
