The system further includes an information signal provider to provide at least one signal to deliver at least some of the attained information to a user. As an example, from the delivered information the user can decide whether or not to answer the incoming call. In another embodiment, the system further includes an alert signal provider to provide a signal to alert the user and an activator to receive instruction from the user. The information signal provider operates responsive to the activator. This embodiment answers an incoming call, attains information from the caller, alerts the user, the user then instructs the activator and the signal provider responds and delivers attained information to the user.
