  • Patent number: 6236724
    Abstract: A method of generation and detection of acoustic signals carrying alpha-numeric data for reducing the effects of noise and thereby improving signal transmission without the need to boost the power of the signal. In accordance with one aspect of the invention, a special DTMF acoustic signal consisting of a combination of two frequencies will be generated for the representation of a particular alpha-numeric character that will be similar to the standard DTMF tone. The difference between the amplitudes of both frequencies varies during the time of generation of the DTMF tone in such a way that both signals will arrive at a final destination detector, i.e., an interactive voice response board, at least for a portion of the generation time, at a relatively similar amplitude, thereby substantially increasing the probabilities of being recognized as a DTMF signal.

  • Patent number: 6195427
    Abstract: In a method for detecting the state of dialling a codenumber a number already dialled digits (Nx) is counted and is compared with a defined number of digits to be dialled. If this number is reached, a timer (Tx) is started and during the runtime of the timer it is detected whether further digits are dialled. If further digits are dialled the timer is restated at every detection. If no further digit is detected, after time out of the timer a query is launched. Alternatively after launching a first query it is possible to analyse the already dialled number of digits and to define a number of digits to be dialled. If then this number is reached a timer is started and the further method is processed.

    Abstract: A predictive dialing system having a computer connected to a telephone switch stores a group of call records in its internal storage. Each call record contains a group of input parameters, including the date, the time, and one or more workload factors. Workload factors can indicate the number of pending calls, the number of available operators, the average idle time, the connection delay, the completion rate, and the nuisance call rate, among other things. In the preferred embodiment, each call record also contains a dial action, which indicates whether a call was initiated or not. These call records are analyzed by a neutral network to determine a relationship between the input parameters and the dial action stored in each call record. This analysis is done as part of the training process for the neutral network.

  • Patent number: 4953201
    Abstract: An additional piece of telephone equipment for protecting against nuisance calls as a substitute for a telephone answering device, wherein after the equipment is engaged upon reception of an incoming call, one or the other of a dummy busy tone or a dummy ringback tone is randomly sent out to a calling party, so that it is possible to inform the calling party in a natural way that a called party cannot answer the calling party now. At this time, according to an even or odd number of value of a counter in a microprocessor (CPU), the dummy busy tone or the dummy ringback tone is sent out, and for this purpose, a random-number command stored in the program is used to select the above even or odd number.

  • Patent number: 4932046
    Abstract: A system automates interface intervals with remote telephone terminals as to provide information or advice in response to select tone signals formed at a telephone terminal, and at the conclusion of an interval provides a disconnect or termination signal prompting a caller to "hang up". Disconnect signals simulate known sounds, specifically as the "click" attendant a remote "hang up" and the traditional dial tone. The disconnect signals are transmitted to a caller after an interface interval to prompt the caller to "hang up" and release the telephone line connection.

  • Patent number: 4645881
    Abstract: The method includes generating a binary signal (S4A to S4D) which is time modulated. To do this, an alternating signal (S1) is compared with a known cyclical signal (S5) and a threshold signal. There is measured the durations between the transitions of the modulated signal by means of a high speed clock and by means of counting in the positive and negative directions of the clock pulses for one or more periods of the signal under examination. If, after counting, a residual value is found, one generates a binary signal representing the transition.
