Grandstream recommends to read Release Notes document which may include special firmware upgrade notices and always keep your devices up-to-date by upgrading their firmware versions regularly.

This document describes steps needed to upgrade Grandstream devices firmware version and covers following scenarios:

  • Scenario 1: Upgrade using Grandstream Public HTTP Server.
  • Scenario 2: Upgrade using local HTTP/HTTPS/TFTP Server.
  • Advanced options.

Scenario 1: Upgrade using Grandstream Public HTTP Server

Grandstream is hosting latest firmware files in a public HTTP server so customers can use it to directly upgrade their Grandstream devices with latest firmware. The same server hosts also BETA firmware when available.

Follow below steps to successfully upgrade your device:

  1. Access web interface of your device and go to MaintenanceUpgrade and Provisioning settings page
  2. Make sure to select “Always Check for New Firmware”.
  3. Under “Firmware”, Select Upgrade via HTTP.
  4. Enter “firmware.grandstream.com” under Firmware Server Path.
  5. Press Save and Apply button to apply the new settings.
  6. Reboot the device and wait until the upgrade process is completed.

Notes:

  • To upgrade using Grandstream HTTP server, the device needs to be connected to Internet.
  • To upgrade to BETA firmware (if available), use “firmware.grandstream.com/BETA” in step 4.

Scenario 2: Upgrade using Local HTTP/ HTTPS/TFTP Server

Customers can use their own HTTP, HTTPS or TFTP server to upgrade Grandstream devices.

To achieve this, first download firmware files for the appropriate device model from http://www.grandstream.com/support/firmware. Unzip downloaded package and put extracted files in the root directory of your server.

Notes:

  • Devices and your server needs to be in same LAN.
  • If using remote server, make sure to open/redirect ports in your router, so devices can download firmware files from it.

Reminder:

HTTP (TCP) default port is 80, HTTPS (TCP) default port is 443 and TFTP (UDP) default port is 69.

ADVANCED OPTIONS

Automatic Upgrade

Automatic Upgrade allows to periodically check if a newer firmware is available to download and upgrade the device. This option will help to keep the devices up-to-date.

Automatic Upgrade can be enabled from web configuration interface  Upgrade and provisioning settings.

Figure 21: Example of Configuring Automatic Upgrade on GXP21xx

The automatic upgrade can be configured based on following options:

  • Every interval in minute(s)
  • Every day (“Hour of the Day” should be configured)
  • Every week (“Hour of the Day” and “Day of the Week” should be configured, 0 is Sunday) If the firmware is available, it will be downloaded and the device will be upgraded automatically.

Firmware File Prefix and Postfix

Firmware prefix and postfix are two options which can be configured by users to lock the firmware update, then only the firmware with the matching prefix and/or postfix will be downloaded and flashed into phone.

Firmware file prefix and postfix can be configured from web GUI Maintenance Upgrade and provisioning.

Use Case Example:

Using firmware prefix and postfix, users store different firmware versions in same folder and upgrade to specific version.

  • If Firmware File Prefix is set to 1.0.3.14 on GXP1600 series phone, for example, requested firmware file will be 1.0.3.14gxp1600fw.bin
  • If Firmware File Postfix is set to 1.0.2.22 on GXP1600 series phone, for example, requested firmware file will be gxp1600fw.bin1.0.2.22

HTTP/HTTPS User Name and Password

HTTP/HTTPS User Name and Password need to be configured if HTTP/HTTPS server requires authentication to access and download firmware files.

To begin firmware upgrade process, the phone sends an initial request to download firmware files from the server, the request will be challenged by the server to provide valid credentials, the phone sends same request including configured HTTP/HTTPS User Name and Password, if accepted, firmware upgrade process can start.

If Always Authenticate Before Challenge is set to “Yes”, the phone includes configured credentials in initial request to download firmware files before being challenged by the server. The default setting is “No”.
