  • Patent number: 6115464
    Abstract: A method and system for distinguishing valid DTMF signals from spurious DTMF noise includes detecting signals having a first signal component indicative of DTMF signals and having a second signal component having frequencies unrelated to DTMF frequencies. The second component is utilized in isolation from the DTMF frequencies of the first signal component. The analysis includes determining a signal level representative of the second signal component. If the signal level exceeds a predetermined threshold level, the first signal component is determined to be spurious noise. On the other hand, if the signal level is below the threshold level, the first signal component is passed to a DTMF-responsive system, such as a voicemail system or a voice response unit. Optionally, the operation includes requesting confirmation of the signal of interest, if the signal level of the second signal component falls within a range which includes the threshold level as its upper limit.

In a first embodiment, the screener generates a random single digit number, and requests the caller to press this number key on their phone to verify compliance with the previously read message. Depending on the caller's actions, the call is either disconnected, or is allowed to ring through to the user's telephone. Neither the caller nor the screener user needs to know any predefined codes. Further, the screener does not depend on any Caller ID system or telephone answering machine.

  • Patent number: 5671268
    Abstract: A telephone answering machine includes at least two tapes, the first of which records a subscriber's outgoing universal message (OGM) to all callers. A second of the two tapes records incoming messages from callers. A control device detects a tone code defined by, and entered by, a caller in conjunction with recording one of the messages as a message from the caller. The second tape is rewound and plays back the recorded caller's message to the subscriber. The subscriber can then re-enter the same code and record a response to the recorded caller's message on the first tape. The control device detects the code being re-entered by the caller if the caller has called again, in search of the response recorded by the subscriber, which corresponds to the re-entered code. The control device further searches for the re-entered code on the first tape in conjunction with the response recorded by the subscriber in response to the caller having re-entered the code.

  • Patent number: 5633917
    Abstract: A controller circuit enables remote control of conventional answering machines from any telephone coupled to the same telephone line to which the answering machine is coupled, and within the same dwelling (such a telephone herein sometimes called a "local remote-control" telephone). The controller in a first mode of operation is transparent to the answering machine and to the normal operation of the local remote-control telephone. When activated by a DTMF security code transmitted from the local remote-control telephone, the controller enters a second (local remote-control) mode of operation which causes the answering machine to pick up the line as if answering a call. DTMF signals transmitted by the local remote-control telephone are coupled by the controller to the answering machine for enabling remote control operation of the machine (e.g., to retrieve recorded messages).

  • Patent number: 5572576
    Abstract: A telephone answering device (TAD) which includes a means of intelligently organizing voice messages, associated entered codes such as personal IDs and home telephone numbers, and information stored in the memory of the TAD. These codes or numbers are decoded by means of the caller entering DTMF signals into the telephone which are recognized, recorded and processed by the TAD. When processed with codes and personal information previously entered into the device's memory, the TAD displays the identity of the callers for each message, thus providing a menu of choices, i.e., a list of callers. This enables the user to access messages in a selective manner based on the identity of the caller. The need to listen to the actual voice messages to determine the caller's identity and the need to listen to the messages sequentially or chronologically is obviated, saving both time and effort.

  • Patent number: 5568539
    Abstract: An interactive telephonic message delivery method and apparatus for providing an intended recipient of a voice message with options as to when the intended recipient will hear the message. Initially, the recipient of the voice mail is directed to indicate that he or she has a touch-tone telephone by generating a recognizable tone through pressing any one of the telephone touch-tone buttons. If the recipient does not generate a recognizable tone before the expiration of a predetermined amount of time, the recipient is informed of a telephone number to dial at a later time from a touch-tone telephone in order to retrieve the message. On the other hand, if the recipient indicates that he or she possesses a touch-tone telephone (i.e., if the recipient generates a recognizable tone), the recipient is then provided with a number of options for processing the message. The recipient then selects particular options by pressing the telephone buttons associated with the particular options.

  • Patent number: 5550900
    Abstract: A telephone message system overcomes the problems and limitations of presently available systems that seek to enhance inter-and intra-premises communications. The system comprises a controller unit with Caller ID capabilities and one or more adjunct units that are all bridged onto a single wire-pair at a user's residential location in a parallel electrical connection. For facilitating a message routing capability, a mailbox of groups of telephone numbers are associated with a particular party at the residence. These telephone numbers are preprogrammed into the controller unit so that upon receipt of an incoming call from one of these telephone numbers, identified through caller ID, the incoming call is associated with the particular called party and the controller unit routes the incoming call directly to the called party's mail box where the calling party is able to leave a message.
