Abstract
Abstract A telephone answering machine adapted for use in conjunction with a telephone system having a station-to-station call transfer capability for incoming calls includes a tape deck and various components for recording and playing back announcements and messages under microprocessor control. The answering machine also includes a DTMF receiver and DTMF generator for receiving and sending digit tone signals. The microprocessor directs the operation of the answering machine for recording data from a calling party, which data represent a telephone number to which the calling party wishes to be transferred. Thereafter, the microprocessor directs the operation of the answering machine for dialing this telephone number after a hook flash has been used to request a call transfer sequence by the telephone system. The telephone answering machine thereby enables call transfers to take place upon the initiative of calling parties.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
226 words
A telephone answering machine connectable to any selected one of a plurality of telephone station lines of a telephone switching system, wherein the telephone system connects a caller's outside telephone line with a telephone station line designated by the caller, and wherein the telephone system initiates the connection by providing a signal on the caller-designated telephone station line, the telephone answering machine comprising: message means for receiving and transmitting messages; interface means connected to a first telephone station line for connecting the message means with the first telephone station line in response to a first signal provided on the first telephone station line by the telephone system, the connection being made in the absence of signals generated by the caller subsequent to the first signal; control means for enabling the message means to receive or transmit messages over the first telephone station line and for monitoring the first telephone station line to detect a second signal generated by a caller whose outside line is connected with the first telephone station line, wherein the second signal includes an extension number for a second telephone station line; and transfer means for storing the extension number included in the second signal and for retrieving the stored extension number to generate transfer signals suitable for directing the telephone system to transfer the outside caller to the second telephone station line.
Claim 2
Dependent Claim
226 words
A telephone answering machine connectable to any selected one of a plurality of telephone station lines of a telephone switching system, wherein the telephone system connects a caller's outside telephone line with a telephone station line designated by the caller, and wherein the telephone system initiates the connection by providing a signal on the caller-designated telephone station line, the telephone answering machine comprising: message means for receiving and transmitting messages; interface means connected to a first telephone station line for connecting the message means with the first telephone station line in response to a first signal provided on the first telephone station line by the telephone system, the connection being made in the absence of signals generated by the caller subsequent to the first signal; control means for enabling the message means to receive or transmit messages over the first telephone station line and for monitoring the first telephone station line to detect a second signal generated by a caller whose outside line is connected with the first telephone station line, wherein the second signal includes an extension number for a second telephone station line; and transfer means for storing the extension number included in the second signal and for retrieving the stored extension number to generate transfer signals suitable for directing the telephone system to transfer the outside caller to the second telephone station line.
Claim 3
Dependent Claim
35 words
The machine of claim 1 wherein the control means and interface means are associated for permitting a caller to recite a message for receipt by the message means before the caller generates a second signal.
Claim 4
Dependent Claim
53 words
The machine of claim 2 wherein the interface means includes audio transmission means for providing transmission of audio signals over the first telephone station line to the message means in response to the first signal, the control means interrupting the transmission of audio signals whenever the caller begins to generate a second signal.
Claim 5
Dependent Claim
13 words
The machine of claim 1 wherein the first signal is a ring signal.
Claim 6
Independent Claim
203 words
A method for operating a telephone answering machine that is connectable to any selected one of a plurality of telephone station lines of a telephone switching system, wherein the telephone system connects a caller's outside telephone line with a telephone station line designated by the caller, and wherein the telephone system initiates the connection by providing a signal on the caller-designated telephone station line, the method comprising the steps of: connecting a first telephone station line to a message mechanism for receiving and transmitting messages, wherein the connection is made in response to a first signal provided on the first telephone station line by the telephone system and wherein the connection is made in the absence of signals generated by the caller subsequent to the first signal; monitoring the first telephone station line to detect a second signal generated by the caller whose outside line is connected with the first telephone station line, wherein the second signal includes an extension number for a second telephone station line; storing the extension number included in the second signal; and retrieving the stored extension number to generate transfer signals suitable for directing the telephone system to transfer the outside caller to the second telephone station line.
Claim 7
Independent Claim
203 words
A method for operating a telephone answering machine that is connectable to any selected one of a plurality of telephone station lines of a telephone switching system, wherein the telephone system connects a caller's outside telephone line with a telephone station line designated by the caller, and wherein the telephone system initiates the connection by providing a signal on the caller-designated telephone station line, the method comprising the steps of: connecting a first telephone station line to a message mechanism for receiving and transmitting messages, wherein the connection is made in response to a first signal provided on the first telephone station line by the telephone system and wherein the connection is made in the absence of signals generated by the caller subsequent to the first signal; monitoring the first telephone station line to detect a second signal generated by the caller whose outside line is connected with the first telephone station line, wherein the second signal includes an extension number for a second telephone station line; storing the extension number included in the second signal; and retrieving the stored extension number to generate transfer signals suitable for directing the telephone system to transfer the outside caller to the second telephone station line.
