Software Upgrade

7.1

Upgrade through TFTP

To upgrade software, HandyTone-488 can be configured with a TFTP server where the new code
image is located. The TFTP upgrade can work in either static IP or DHCP mode using private or public
IP address. It is recommended to set the TFTP server address in either a public IP address or on the
same LAN with the HandyTone-488.
There are two ways to set up the TFTP server to upgrade the firmware, namely through voice menu
prompt or via the HandyTone-488's Web configuration interface. To configure the TFTP server via
voice prompt, follow section 5.1 with option 06, once set up the TFTP IP address, power cycle the
ATA, the firmware will be fetched once the ATA boots up.
To configure the TFTP server via the Web configuration interface, open up your browser to point at
the IP address of the HandyTone-488. Input the admin password to enter the configuration screen.
From there, enter the TFTP server address in the designated field towards the bottom of the
configuration screen.
Once the TFTP server is configured, please power cycle the HandyTone-488.
TFTP checking is only performed during the initial power up. If the configured TFTP server is found
and a new code image is available, the HandyTone-488 will attempt to retrieve the new image files by
downloading them into the HandyTone-488's SRAM. During this stage, the HandyTone-488's LED
will blink until the checking/downloading process is completed. Upon verification of checksum, the
new code image will be saved into the Flash. If TFTP fails for any reason (e.g., TFTP server is not
responding, there are no code image files available for upgrade, or checksum test fails, etc), the
HandyTone-488will stop the TFTP process and simply boot using the existing code image in the flash.
TFTP process may take as long as 1 to 2 minutes over the Internet, or just 20+ seconds if it is
performed on a LAN. Users are recommended to conduct TFTP upgrade in a controlled LAN
environment if possible. For those who do not have a local TFTP server, Grandstream provides a
NAT-friendly TFTP server on the public Internet for firmware upgrade. Please check the Service
section of Grandstream's Web site to obtain this TFTP server's IP address.
NOTES:
When HandyTone ATA boot up, it will send TFTP or HTTP request to download configuration files,
there are two configuration files, one is "cfg.txt" and the other is "cfg000b82xxxxxx", where
"000b82xxxxxx" is the MAC address of the HandyTone ATA. These two files are for initial
automatically provisioning purpose only, for normal TFTP or HTTP firmware upgrade, the following
error messages in a TFTP or HTTP server log can be ignored.
TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does not exist
TFTP Error from [IP ADRESS] requesting cfg.txt : File does not exist
