ABSTRACT:
A fully automatic communication system employing an automatic telephone answering device and a mobile radio transmitter and receiver for enabling a party calling another on the telephone to communicate to the mobile location of the other in "real time" that the call is being made and to relay the telephone number of the calling party. This enables the party being called to directly "telephone" back to the calling party without the need for first communicating with the telephone answering device.
In a more enhanced form, the system further permits the mobile party being called to acknowledge the reception of the call by transmitting an acknowledgment signal back to the telephone answering device to, in turn, notify the calling party that his call and calling number has been received by the party being called.
