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/1.1.0.31

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.

• Grandstream recommends end-user use the Grandstream TFTP server. Its address can be found

at http://www.grandstream.com/firmware.html

. Currently the TFTP firmware server IP address

is 168.75.215.189. For large companies, we recommend to maintain their own TFTP/

HTTP/HTTPS server for upgrade and provisioning procedures.

• 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

Instructions to download a free TFTP Server

1. Unzip the file and put all of them under the root directory of the TFTP server.
