Abstract: In caller ID telephone service system, if a calling party does not want to display his telephone number on the called party side, the calling party takes an authorized key number (hereinafter called "blocking key number") with the telephone exchange office. The key number is composed of a 3 or 4 digit numerical signal, like a push-phone tone, when the subscriber calls any subscriber (called party) telephone number in this service area. If he dials that key number first and then the conventional number, the telephone exchange office detects that key number, then blocks (stops) sending the calling party telephone number to the called party side. On the other hand, the called party side has a device with a relay which functions to take out the associated telephone set from the telephone line after one ring because the device cannot detect telephone number information between the first ring and second ring.

Abstract: A system combines a telephone answering device, or TAD, installed at each subscriber's premises and a voice mail center station. When IC memory is used as recording media of the TAD to record messages from a calling party, the memory becomes full to its capacity shortly, and the TAD cannot fulfill its function. To prevent this, a voice mail side is set to a message-receiving mode and an incoming message, or ICM, is transferred from the TAD side to the voice mail side by calling the voice mail side and receiving a particular signal from the TAD side. Then, the TAD restores its function and becomes capable of recording new ICMs. It was a common usage of the voice mail center that a calling party directly records ICMs in the voice mail center. In this system, however, an ICM stored in the voice mail center can be transferred to the TAD by controlling from the TAD as occasion demands, and the ICM can be stored in the TAD.
