We have identified that there are a number of devices using old firmware – this is software that runs on the phone in order to make it work.

In order to keep our customers’ hardware up-to-date with security essentials and to ensure seamless functionality across our continuously improving platform, we will be rolling out the following firmware upgrades throughout the hours of 2:00am-4:00am over the next four weeks.

If you’re planning on using the phones at this time, please be sure to let the firmware upgrade complete before powering off or re-using the device. The update will appear clearly on the phone’s screen during the process, so you’ll know for certain when it’s finished.

Gigaset Dect 

Full upgrade across the platform to firmware version 76

Gigaset Desk
