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.
Note
This section mainly introduces IPv4 network parameters. IP phones also support IPv6. For
more information on IPv6, refer to
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.
Procedure
DHCP can be configured using the configuration files or locally.
