ABSTRACT:
A security system is configured to enable and disable telephone functions in response to changes in the operational state of the system, such as fully armed, partially armed and disarmed. When the system changes its operational state, it automatically sends a command to change the implementation of a telephone function, such as call forwarding. The system includes an input device for setting the system to a selected state, an interface for communicating with the telephone service provider and a controller for initiating communications through the interface and sending a command to change the telephone function.
