Abstract
Abstract A telephone set adapted to provide the calling person with a convenient grip of the hand set. The seat accommodating the handle is shaped as a channel whose sides surround the handle along its middle part so that the person making the telephone call cannot seize this part but, instead, will seize the lower (microphone) part.
