7Software Upgrade
7.1Upgrade through HTTP
To upgrade software, HandyTone-488 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/1.0.0.4
Where firmware.mycompany.com is the FQDN of the HTTP server, “:6688” is the TCP port the HTTP server listening to, “/Grandstream/1.0.0.4” is the RELATIVE directory to the root dir in HTTP server. Thus, you can put different firmware into different directory as well.
Note: 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.
7.2Upgrade 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, 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 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 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
