Abstract
A residential phone system allows for local control of call features from any phone extension. The phone system may include a microcontroller that communicates along the phone lines at a non-utilized frequency to several extension phones in a residence. The microcontroller permits each phone to control call features such as call waiting, conference calling, paging, or other features. A control box may be included at any or all of the extension phones to provide a convenient user interface to access the call features.
