Claims
- 1. 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.
- 2. 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.
- 3. 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.
- 4. The machine of claim 1 wherein the first signal is a ring signal.
- 5. 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.
- 6. The method of claim 5 further including the step of connecting the first telephone station line with the message mechanism to permit a caller to recite a message for receipt by the message mechanism before the caller generates a second signal.
- 7. The method of claim 5 further including the steps of connecting the first telephone station line with the message mechanism to permit transmission of audio signals over the first telephone station line to the message mechanism in response to the first signal, and interrupting the transmission of audio signals whenever the caller begins to generate a second signal.
- 8. The method of claim 5 wherein the first signal is a ring signal.
