The invention is a telephone answering device that permits the number of rings before the call is answered, and the speaker volume, to be programmed to vary depending on the time of day and day of the week, or to be set at desired levels for specific lengths of time. The device contains a timer 19 and a microcomputer 10, said microcomputer 10 having a programmable ring register 23 and a programmable speaker register 24. A program ring button 25, a program speaker button 26, a time ring button 27, a time speaker button 28, a plus button 29, and a minus button 30 located on a control module 14 enable the user to access programmable ring register 23 and programmable speaker register 24, to set the number of rings before answering and the speaker volume. Incoming telephone calls are handled by a ring detector circuit 13 and microcomputer 10. When the number of cumulative ring signals matches the appropriate programmed setting, the incoming call is sent to an answering apparatus 18. Microcomputer 10 then sets the volume of a speaker 16 to the appropriate programmed setting, via a volume control circuit 17.
