ABSTRACT:
A telephone answering machine (TAS) is preprogrammed to place calls automatically to a service bureau (SB) over a telephone or other suitable communications network. In response to the calls, the SB generates and transmits messages (e.g., compressed digital audio messages) to the TAS for recording and subsequent playback by a user. In this way, users can routinely receive information useful to their daily lives.
