Software Configuration

Software upgrades are completed via TFTP or HTTP. The corresponding configuration settings are in the
ADVANCED SETTINGS configuration page.

PGRADE THROUGH
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 URLs:
firmware.mycompany.com: 6688/Grandstream/1.0.0.18
168.75.215.190
There are two ways to set up the Upgrade Server to upgrade firmware: IVR and Web Configuration
Interface.
IVR M
ETHOD
Firmware server in IP address format can be configured via IVR. 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, please update the settings and reboot
the device. The HT–496 retrieves the new image files by downloading them into the HT–496's SRAM
While downloading, the HT–496's LEDs will blink until the checking/downloading process is completed.
Upon verification of checksum, the new code image is saved into the Flash. If the 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 HT–496 will stop the TFTP/HTTP process and re-boot using the
existing code image in the flash.
The firmware upgrade may take as long as 20 minutes over Internet, or 20+ seconds if using a LAN.
Grandstream recommends a controlled LAN environment for firmware upgrades 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. Check
