Abstract: A method and apparatus for providing control and monitoring of a group of plain old telephone service (POTS) stations from one control station. Incoming calls to the POTS stations are intercepted and the data describing the call is sent to the control station. The control station then provides directions for blocking the call, completing the call to the original POTS destination, or completing the call to another POTS destination. Outgoing calls are also monitored so that the control station maintains an up to date record of which stations are busy and which stations are idle. Advantageously, the control station communicates with the switch serving these POTS stations by analog signals (FSK) and/or DTMF thus overcoming the limitations on distance requirements for digital signaling.
