7 Software Upgrade
Software upgrade can be done via either TFTP or HTTP. The corresponding configuration settings are
in the ADVANCED SETTINGS configuration page.
7.1 Firmware Upgrade through TFTP/HTTP
To upgrade via TFTP or HTTP, the “Firmware Upgrade and Provisioning upgrade via” field (IVR
option 17) needs to be set to TFTP or HTTP, respectively. “Firmware Server Path” needs to be set to a
valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here
are examples of some valid URL.
e.g. firmware.mycompany.com:6688/Grandstream/1.0.8.32
e.g. 168.75.215.189
NOTES:
• Firmware server in IP address format can be configured via IVR. Please refer to section 5.1 for
instructions. If firmware server is in FQDN format, it must be set via web configuration
interface.
• Once a “Firmware Server Path” and the upgrade protocol are set, user needs to update the
settings and reboot the device. If the configured firmware server is found and a new code image
is available, the HandyTone ATA will attempt to retrieve the new image files by downloading
them into the HandyTone ATA’s SRAM. During this stage, the HandyTone ATA’s LEDs will
blink until the checking/downloading process is completed. Upon verification of checksum, the
new code image will then be saved into the Flash. If TFTP/HTTP fails for any reason (e.g.,
TFTP/HTTP server is not responding, there are no code image files available for upgrade, or
checksum test fails, etc), the HandyTone ATA will stop the TFTP/HTTP process and simply
boot using the existing code image in the flash.
• Firmware upgrade may take as long as 1 to 20 minutes over Internet, or just 20+ seconds if it is
performed on a LAN. It is recommended to conduct firmware upgrade in a controlled LAN
environment if possible. For users who do not have a local firmware upgrade server,
Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware
upgrade. Please check the Services section of Grandstream’s Web site to obtain our public
TFTP server’s IP address.
• Alternatively, user can download a free TFTP or HTTP server and conduct local firmware
upgrade. A free windows version TFTP server is available for download from
http://support.solarwinds.net/updates/New-customerFree.cfm
. Our latest official release can be
downloaded from http://www.grandstream.com/y-firmware.htm. Unzip the file and put all of
them under the root directory of the TFTP server. Put the PC running the TFTP server and the
HandyTone ATA in the same LAN segment. Please go to File -> Configure -> Security to
change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the
firmware upgrade. Start the TFTP server, in the HandyTone ATA’s web configuration page,
configure the Firmware Server Path with the IP address of the PC, update the change and
reboot the unit. Please be advised that our client will pull out firmware from the WAN side, if
