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.
