Landline telephones, answering machines
Landline telephones and answering machines are linked to a fixed base in a household or workplace. A distinction can be made between corded and cordless telephones.
Operation is simplified by large keys or voice control. Call signals can be acoustic, optical or tactile. Videophones and writing telephones allow text or video transmission. Simple operating functions and extra emergency call buttons help to achieve intuitive control. Answering machines are integrated in most systems and can be activated or deactivated.
