发明名称 SHARED LINE TELEPHONE ANSWERING DEVICE
摘要 For a single telephone line having plural telephone answering devices (TADs) connected to it, a system of TADs is disclosed where only one TAD answers the telephone but all other TADs connected to the telephone line are accessible and activated by means of tones transmitted over the telephone line by the caller. The caller is notified by the answering TAD of the available tone codes which are then used to select the desired TAD. When a TAD is selected by means of tones, the first TAD is temporarily disconnected from the telephone line so that message privacy is maintained.
