Easy installation thanks to PoE. This network-enabled device is powered via Power over Ethernet (PoE) through the LAN cable. The main advantage of PoE is that you do not need a power supply cable. This allows you to install Ethernet-connected devices in hard-to-reach places or in areas where many cables would be disruptive. You save on installation costs and can increase the reliability of connected devices by using a central uninterruptible power supply (UPS) if desired. Mobile and flexible thanks to EHS connection. Connect a cordless headset to the phone using Electronic Hook Switch (EHS): This allows you to handle calls solely with the headset without having to stay near the phone. Calls are also signaled directly on the headset. If you are near your phone, you can transfer the ongoing conversation to the regular handset. You do not need mechanical aids, such as a handset lifter, for this.
