Updating Grandstream Firmware


Note: It is not necessary to track an end user's devices and update their IP phones every time a new firmware version is released by Grandstream. It is recommended when issues are apparent and helping the end user is required. This will assist in consistency when troubleshooting such issues. The information found here will always be based on the most recent release.

Setting the phone to upgrade firmware via the Device section in the portal:

  • Navigate to the device page for the phone you want to upgrade under PBX and Devices.
  • Scroll down and click Submit again for the overall device configuration.
  • Reboot the phone.

After allowing the device to reboot completely, wait 60 seconds and the upgrade process will begin. The process has begun when the screen displays a progress bar and text related to a firmware upgrade in process. It is very important to not disconnect the power or LAN cable to the phone until this process is complete.

Alternatively, the firmware files for the phone can be downloaded at fw.cytracom.com . Once downloaded, upload the *.bin file to the web interface of the phone by going to the IP address.

Once Logged in, go to:

  • Maintenance
  • Upgrade and Provisioning
  • Click on Start to the right of Firmware Upgrade

The option will be given to select and upload the previously downloaded firmware file. Feel free to email support with any questions, support@cytracom.com.
