Abstract: A technique for improved DTMF detection utilizes a speech detector, either alone or in combination with other information from a voice processing arrangement, to adjust the sensitivity of the DTMF detector. The DTMF detector is turned completely off when the voice processing application is in the record mode, and when speech is detected.

Abstract: Method and apparatus for recovering in-bound calls to a call center, which in-bound calls were directed to overflow. An embodiment of the inventive method includes the steps of: logging telephone numbers of in-bound calls that overflow the handling capacity of the call center, which telephone numbers are provided by the signaling capacity of the network to the call center; determining when call center agents become available; automatically initiating calls back to the logged telephone numbers; detecting when calls are answered; and causing call center agents to be connected thereto.

Abstract: ANI Blocking System (ABS) logically interfaces between a calling party and a called party in a telephone network which provides CallerID and CallerID blocking. The ABS automatically: (1) accepts a call from the calling party; (2) places a call to the called party; and (3) connects the called party with the calling party.

Abstract: Apparatus and method for measuring the transmission quality of a telephone line, for example, a telephone line connected between two voice processing systems. The apparatus includes means for generating a predetermined sequence of DTMF pulses having predetermined amplitude values and for transmitting them over a telephone line; means for receiving DTMF pulses from a telephone line and determining the value of each pulse; means for counting the number of received DTMF pulses; and means for comparing the number with a predetermined threshold value, whereby the telephone line is determined to have acceptable transmission quality if the number exceeds the predetermined threshold value. Further, in a preferred embodiment, the predetermined sequence of DTMF pulses comprises four groups of ten (10) DTMF pulses, each of which groups has succeedingly lower amplitude.

Abstract: A Call Filter System (CFS): (1) logically interfaces between a public telephone network and business customer premises equipment; (2) automatically processes incoming and outgoing calls which are amenable to such intervention; and (3) enlists the aid of human intervention on calls requiring such intervention. The CFS includes a network line interface (NLI) for receiving calls from and placing calls to the public telephone network; a premises line interface (PLI) for receiving calls from and placing calls to the business customer premises equipment; a voice processing means (VPM) which is switchably interconnected to the NLI and/or the PLI for translating audio signals transmitted thereto from the NLI or PLI and for transmitting audio signals to the NLI or PLI; a connection and switching means (CSM) for connecting and switching the NLI to either the PLI or VPM and for connecting and switching the PLI to either the NLI or VPM; and a controller for directing the activities of the NLI, PLI, VPM and CSM to automatically process incoming calls to and outgoing calls from the CFS.
