Much more than a conventional call blocking list: With the Gigaset E720, you can set the display to light up green for known callers, making trusted individuals easily recognizable at a glance. To do this, simply add these individuals to the internal phonebook and activate the assistance feature for legitimate callers in the menu. Alternatively, you can opt for an even stricter call protection and allow only known callers to get through from the start. A special feature of the Gigaset E720 family is the direct dialing for emergencies: You can set up to 15 contacts that will be automatically connected to you when they call. You can then speak to these callers through the hands-free function of your mobile device without having to answer the call yourself.
