Basic Network Settings

In order to get your IP phones running, you must perform basic network setup, such as IP address and subnet
mask configuration. This section describes how to configure basic network parameters for IP phones.
This section mainly introduces IPv4 network parameters. IP phones also support IPv6. For more information on
IPv6, refer to "IPv6 Support".
DHCP
DHCP (Dynamic Host Configuration Protocol) is a network protocol used to dynamically allocate network
parameters to network hosts. The automatic allocation of network parameters to hosts eases the administrative
burden of maintaining an IP network. IP phones comply with the DHCP specifications documented in RFC 2131. If
using DHCP, IP phones connected to the network become operational without having to be manually assigned IP
addresses and additional network parameters. Static DNS address (es) can be configured and used when DHCP is
enabled.
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.
