Claim 3

An auto response phone system, as recited in claim 1, further comprising a night switch whereby when said night switch is depressed said digital switch directs the appropriate memory to output its contents via said digital switch to said digital to analog converter, to said preamp, to said power amplifier, and to said speaker, and also to said mixer, thereby outputting a message onto said telephone line, while disabling said electronic ringer switch so that a connected phone's ringer does not operate; and a toner decoder that detects the presence of a predetermined touch tone code sequence and re-enables said electronic ringer switch such that said ringer operates normally.

Claim 4

An auto response phone system, as recited in claim 2, further comprising in signal lamp that lights when said night switch is activated.

Claim 5

An auto response phone system, as recited in claim 1, further comprising a monitor switch that when activated bridges said telephone line to said preamp so that signals transmitted via said telephone line can be automatically monitored.

Claim 6

An auto response phone system, as claimed in claim 2, further comprising a modular jack to attach a conventional modular telephone, a cable with a modular plug to connect with a conventional modular telephone line, and a case to contain all of the elements of the phone system such that the system is an accessory to a conventional modular telephone.

Claim 7

An auto response phone system for electronically answering a telephone with a selectable one of a plurality of pre-recorded messages and for screening calls by selectively blocking and remotely activating a ringer means of the telephone while also providing for the optical audio monitoring of incoming calls, said system comprising controllable logic means and switch means connected to said logic means for controlling said logic means; ring signal detection means and a plurality of erasable message storage means connected to said logic means; said ring signal detection means being coupled to a telephone line such that an incoming call on said telephone line is detected by said ring signal detection means and an indication is transmitted to said logic means; message transmission means connected to said logic means and said telephone line whereby an audio message from a selected one of said plurality of erasable message storage means is selectably transmitted over said telephone line by said logic means; means for selectively recording an audio message on any one of said plurality of erasable message storage means; audio monitor means, ring disable/enable means, and tone decoder means; said logic means selectively connecting said audio monitor means to said telephone line when a call has been detected by said ring signal detection means and said switch means have been switched to allow audio monitoring; said ring disable/enable means being connected to the ringer means of said telephone and to said logic means for selectively enabling and disabling said ring means; said tone decoder means being coupled to said telephone line and said logic means such that dialing tones on said telephone line are detected and interpreted by said tone decoder means and transmitted to said logic means; said switch means being connected to said logic means such that switching said switch means selects one of a plurality of functions of said system, said functions including: manually selecting an audio message from one of said plurality of storage means for immediate transmission over said telephone line, selecting a message from one of said plurality of storage means for automatic transmission over said telephone line when a ring is detected by said ring signal detection means, disabling said ringer means and selecting a message from one of said plurality of storage means for automatic transmission over said telephone line when a ring signal is detected by said ring signal detection means and automatically enabling said ringer means when said tone decoder detects a preselected tone or sequence of tones on said telephone line, and selecting a message from one of said plurality of storage means for automatic transmission over said telephone line when a ring is detected by said ring signal detection means and enabling said audio monitor means to monitor transmission on said telephone line.

Claim 8

An auto response phone system for electronically answering a telephone with a selectable one of a plurality of pre-recorded messages and for screening calls by selectively blocking and remotely activating a ringer means of the telephone while also providing for the optical audio monitoring of incoming calls, said system comprising controllable logic means and switch means connected to said logic means for controlling said logic means; ring signal detection means and a plurality of erasable message storage means connected to said logic means; said ring signal detection means being coupled to a telephone line such that an incoming call on said telephone line is detected by said ring signal detection means and an indication is transmitted to said logic means; message transmission means connected to said logic means and said telephone line whereby an audio message from a selected one of said plurality of erasable message storage means is selectably transmitted over said telephone line by said logic means; means for selectively recording an audio message on any one of said plurality of erasable message storage means; audio monitor means, ring disable/enable means, and tone decoder means; said logic means selectively connecting said audio monitor means to said telephone line when a call has been detected by said ring signal detection means and said switch means have been switched to allow audio monitoring; said ring disable/enable means being connected to the ringer means of said telephone and to said logic means for selectively enabling and disabling said ring means; said tone decoder means being coupled to said telephone line and said logic means such that dialing tones on said telephone line are detected and interpreted by said tone decoder means and transmitted to said logic means; said switch means being connected to said logic means such that switching said switch means selects one of a plurality of functions of said system, said functions including: manually selecting an audio message from one of said plurality of storage means for immediate transmission over said telephone line, selecting a message from one of said plurality of storage means for automatic transmission over said telephone line when a ring is detected by said ring signal detection means, disabling said ringer means and selecting a message from one of said plurality of storage means for automatic transmission over said telephone line when a ring signal is detected by said ring signal detection means and automatically enabling said ringer means when said tone decoder detects a preselected tone or sequence of tones on said telephone line, and selecting a message from one of said plurality of storage means for automatic transmission over said telephone line when a ring is detected by said ring signal detection means and enabling said audio monitor means to monitor transmission on said telephone line.
