Purpose
TFTP allows you to transfer files over the
network.
On the Cisco IP Phone, TFTP enables
you to obtain a configuration file specific
to the phone type.
UDP is a connectionless messaging
protocol for delivery of data packets.
The Cisco IP Phone functions much like a traditional analog phone, allowing you
to place and receive telephone calls.
In addition to these traditional telephony features, the Cisco IP Phone includes
features that enable you to administer and monitor the phone as an IP networking
device.

Usage Notes
TFTP requires a TFTP server in
your network, which can be
automatically identified from the
DHCP server. If more than one
TFTP server is running in your
network, you must manually
assign a TFTP server to each
phone locally.
Cisco IP Phones receive and
process UDP messages.
