Gigaset is one of the largest developers of house telephones worldwide. Previously, Gigaset was part of Siemens, but now Gigaset develops, designs, and produces all products itself. Quality, innovation and design are the most important features of a Gigaset phone. In addition, virtually all Gigaset devices are wireless by means of the DECT protocol. Because of this, they can often be expanded with additional handsets.
