Purpose
DHCP dynamically allocates and assigns
an IP address to network devices.
DHCP enables you to connect the IP
phone into the network and become
operational without manually assigning
an IP address or configuring additional
required network parameters.
IP is a messaging protocol that addresses
and sends packets across the network.
RTP is a standard for transporting
real-time data, such as interactive voice
and video over data networks.
TCP is a a connection-oriented transport
protocol.
Chapter 1
An Overview of the Cisco IP Phone
Usage Notes
DHCP is enabled by default. If
disabled, you must manually
configure the IP address, subnet
mask, gateway, and an TFTP
server on each phone locally.
Cisco recommends that you use
DHCP custom option 150. With
this method, you configure the
TFTP server IP address as the
option value. For additional
supported DCHP configurations,
see the Cisco CallManager
System Guide.
To communicate using IP,
network devices must have an
assigned IP address, subnet, and
gateway.
IP addresses, subnets, and
gateways identifications are
automatically assigned if you are
using the Cisco IP Phone with
Dynamic Host Configuration
Protocol (DHCP). If you are not
using DHCP, you must manually
assign these properties to each
phone locally.
Cisco IP Phones use the RTP
protocol to send and receive
real-time voice traffic from other
phones and gateways.
Cisco IP Phones use TCP to
connect to Cisco CallManager
and to access XML services.
