SOFTWARE UPGRADE
Software upgrade can be done via either TFTP or HTTP or HTTPS. The corresponding configuration
settings are in the ADVANCED SETTINGS configuration page.
FIRMWARE UPGRADE THROUGH TFTP/HTTP/HTTPS
To upgrade via TFTP or HTTP/HTTPS, the “Firmware Upgrade and Provisioning upgrade via” field needs
to be set to TFTP HTTP or HTTPS, 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/1.0.0.8
e.g. firmware.grandstream.com
NOTES:
 Firmware upgrade server in IP address format can be configured via IVR. Please refer to the
CONFIGURATION GUIDE section for instructions. If the server is in FQDN format, it must be set
via the web configuration interface.
 Grandstream recommends end-user use the Grandstream HTTP server. Its address can be found
at http://www.grandstream.com/support/firmware . Currently the HTTP firmware server FQDN is
“firmware.grandstream.com”. For large companies, we recommend to maintain their own TFTP/
HTTP/HTTPS server for upgrade and provisioning procedures.
 Once a “Firmware Server Path” is 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 DP715 will attempt
to retrieve the new image files by downloading them into the DP715’s SRAM. During this stage, the
DP715’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/HTTPS fails for
any reason (e.g. TFTP/HTTP/HTTPS server is not responding, there are no code image files
available for upgrade, or checksum test fails, etc), the DP715 will stop the TFTP/HTTP/HTTPS
process and simply boot using the existing code image in the flash.
 Firmware upgrade may take as long as 15 to 30 minutes over Internet, or just 5 minutes 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.
 Grandstream’s latest firmware is available at http://www.grandstream.com/support/firmware .
Oversea users are strongly recommended to download the binary files and upgrade firmware
locally in a controlled LAN environment.
Note: Alternatively, the user can upload the firmware single file from his/her computer using a local
directory. For more instructions see below. Also the 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/support/firmware .
