6 Software Upgrade & Customization
Software (or firmware) upgrade can be done via either TFTP or HTTP. The corresponding configura-
tion settings are in the ADVANCED SETTINGS configuration page.
6.1 Firmware Upgrade through TFTP/HTTP
To upgrade via TFTP or HTTP, user needs to select TFTP or HTTP upgrade method. “Upgrade
Server” needs to be set to a valid URL of a 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/1.0.0.18
e.g. 168.75.215.189
There are two ways to set up the Upgrade Server to upgrade firmware, namely through the Key Pad
Menu or via the GXV-3000’s Web configuration interface. To configure the Upgrade Server via Key
Pad Menu options, select “System Config” from the Main Menu, then select “Upgrade Preferences”.
Under this sub Menu, user can edit Upgrade Server in either an IP address format or FQDN format.
Choose “Save and use TFTP” or “Save and use HTTP” to select upgrade method. And select “Re-
boot” from the Main Menu to reboot the phone.
To configure the Upgrade Server via the Web configuration interface, open up your web browser and
enter the IP address of GXV-3000. Enter the admin password to get into the web configuration inter-
face. In the ADVANCD SETTINGS page, enter the Upgrade Server’s IP address or FQDN in the
“Upgrade Server” field. Select TFTP or HTTP upgrade method. Once these settings are entered, user
needs to update the change by clicking the “Update” button. Then “Reboot” or power cycle the phone,
the firmware files will be fetched upon booting up.
If the configured upgrade server is found and a new code image is available, the GXV-3000 phone will
attempt to retrieve the new image files by downloading them into the phone’s SRAM. During this
stage, the GXV-3000 phone’s LCD will show firmware file downloading process. Upon verification of
checksum, the new code image will be saved into the Flash. If firmware upgrade 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 GXV-3000 phone will stop the upgrading process and simply boot using
the existing code image in the flash.
Firmware upgrading may take as long as 45 minutes over Internet, or just 5 minutes on a controlled
LAN. It is strongly recommended to conduct firmware upgrade in a controlled LAN environment
whenever possible.
For users who do not have local TFTP server, Grandstream provides a NAT-friendly TFTP server on
the public Internet for users to download the latest firmware upgrade automatically. Please check the
Services section of Grandstream’s Web site to obtain this TFTP server IP address:
