Abstract
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.
