This question touches the very heart of what a “telephone” has become. A modern Gigaset is no longer just copper wire and a carbon microphone; it is a miniature computer cradled in a plastic shell, running a real-time operating system that manages DECT radio frequencies, encryption, answering machines, phonebooks, and even IP-based VoIP protocols.
