A remotely accessible telephone control system for connection to a telephone network and method of handling telephonic communications. The system includes a detector for detecting signals on received via the network. A signal generator is responsive to control signals to produce predetermined signals and apply the signals to the network. A memory is provided for storing data and a central processing unit is programmed for monitoring signals detected by the detector, accessing the memory and producing and applying predetermined control signals to the signal generator. The central processing unit also answers an incoming call to the system and transmits a prompt to the caller, and also senses for transmission of an access code. If the access code is sensed, the incoming call is transferred to the subscriber by transmitting appropriate instructions to the network instructing the network to transfer the incoming call independently of the system to a transfer telephone number associated with the subscriber and stored in the memory, and if the access code is not sensed, then the incoming call is disposed of. |

DETAILED DESCRIPTION The present invention provides a remotely accessible telephone control system. In this aspect of the invention the system includes a detector for detecting signals received via a communication port; memory; and a processing unit programmed for monitoring signals detected by the detector and for accessing the memory. The processing unit is also programmed to sense signals provided by the detector indicating the presence of an incoming call to the system from a calling party, cause signals to be generated which to the calling party indicate normal call processing operation but to a knowledgeable caller indicate that the knowledgeable caller can transmit a confidential access code to gain access to a called party, sense for signals provided by the detector corresponding to the transmission of the confidential access code, and if signals corresponding to the confidential access code are sensed, then issuing instructions connecting the incoming call to the called party. The present invention also provides a remotely accessible telephone control system. In this aspect of the invention, the invention includes a detector for detecting signals received via a communications port; a signal generator responsive to control signals to produce predetermined signals and apply the signals to the communications port; memory; and a central processing unit programmed for monitoring signals detected by the detector, accessing the memory and producing and applying predetermined control signals to the signal generator. The central processing unit is programmed to sense signals provided by the detector indicating the presence of an incoming call to the system from a caller, control a prompting device to transmit a prompt to the caller, sense signals provided by the detector corresponding to the transmission of an access code, and if signals corresponding to the transmission of the access code are sensed, then to transfer the incoming call to the subscriber by transmitting appropriate instructions to a switch instructing the switch to connect the incoming call independently of the system to a transfer telephone number associated with the subscriber and stored in the memory
