Manual software download
It is also possible to download the latest version and install the file directly from your computer using the Konftel Upgrade Utility. This can be useful if you have restricted internet access or if a conference phone is not installed and connected to the internet. Another option is to update the software with an SD memory card. (The Konftel 55 uses the same software for updating via an SD card as for updating via the Konftel Upgrade Utility).
