Home telephone Central (Haus Telefon Zentrale - HTZ) will allow multiple phones to share one phone connection. The designed chip is the core of a system that would allow up to 6 phone connections, and one voicemail machine and three controllable outputs. It is possible to make calls in between the local phones, add a password for the outputs.
