Abstract
A device for remotely controlling call forwarding for a given telephone line. The device includes a detection circuit for detecting an incoming call to the given telephone line. If it detects only one or two signals indicating a previous call forwarding initiate setting, it automatically terminates call forwarding and awaits input of a new call forwarding telephone number followed by a security code. If it detects more than four rings, it knows that the call forwarding was not enabled and it is ready to accept the new call forwarding number remotely input along with the security code. After receiving successfully the remotely inserted call forwarding number and security code, it proceeds to reprogram the system with the new call forwarding number. Should any unauthorized user be using the system, it will reprogram with the previously stored call forwarding number.
