7 Software Upgrade
7.1 Upgrade through HTTP
To upgrade software, HandyTone ATAs can be configured with an HTTP server where the new code
image file is located. For example, following URL in the HTTP Upgrade Server:
http://firmware.mycompany.com:6688/Grandstream/1.0.6.2
Here, firmware.mycompany.com is the FQDN of the HTTP server, “:6688” is the TCP port the HTTP
server listening to, “/Grandstream/1.0.6.2” is the RELATIVE directory to the root dir in HTTP web
server. Thus, you can put different firmware into different directory as well.
NOTES:
• To enable HTTP firmware upgrade, “Auto Upgrade” field has to be set to Yes. In addition, the
ATA will check the HTTP server in the number of days that is defined in “Check for new
firmware every” field.
7.2 Upgrade through TFTP
To upgrade software, HandyTone ATAs 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 either in a public IP address or on the
same LAN with the HandyTone ATA.
There are two ways to set up the TFTP server to upgrade the firmware, namely through voice menu
prompt IVR or via the HandyTone ATA’s Web configuration interface. To configure the TFTP server
via IVR and key pad, 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 ATA. 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, power cycle the HandyTone ATA to start TFTP upgrade.
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 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 in red until the checking/downloading process is completed. Upon verification of
checksum, the new code image will then 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
