Introduction

A Trivial File Transfer Protocol (TFTP) Server may be required in an IP

Telephony system to distribute firmware to IP Phones. The TFTP Server

can reside on a subnet other than the Call Server and can be located on

either side of the firewall.

TFTP Server planning

CAUTION

TFTP firmware download does not work when the IP Audio

Conference Phone 2033 is behind a NAT Server.

The TFTP Server holds the firmware for updating the IP Phones.

Assuming the IP address for the TFTP Server has been configured on the

IP Phone, each time the IP Phone is powered on, rebooted, or is manually

reset, the IP Phone checks the version of firmware against the version of

firmware on the TFTP Server. If the versions are different, the IP Phone

downloads the new firmware from the TFTP Server.
