  • Patent number: 8761372
    Abstract: The present invention is directed to systems and methods of personalizing a self-service option for customers. Customers are identified at call inception and the self-service channel is personalized to tailor the caller experience based upon information specific to each customer. The systems and methods of telephone channel personalization is company/provider driven, which allows the provider to control and personalize the caller experience based on criteria set by the provider. The telephone channel personalization systems and methods determine what choices to present to the caller (i.e., in a speech self-service application—what to say and how to say it). A personalized self-service channel reduces call time and enhances the caller experience and therefore is an attractive option for businesses utilizing a call-center model. The personalized self-service application caters to the needs of a particular customer and appears to the customer that the provider knows why they are calling.

  • Patent number: 6748071
    Abstract: An incoming call received in a private branch exchange (PBX) or other communication system switch at an external port of the switch is processed by the switch so as to appear to a destination terminal as if it were originated by an internal extension associated with the switch. The incoming call may be from a mobile telephone or other originator terminal that is utilizable external to a premises serviced by the switch and does not have an extension associated with any internal endpoint serviced by the switch. The switch attempts to map an identifier associated with the incoming call to a corresponding entry in a stored list of external endpoints registered with the switch. If the identifier has a corresponding entry on the list, the switch processes the incoming call such that it appears to the destination terminal as being originated by an assigned internal extension. For example, an internal alerting indicator and associated station display may be provided at the destination terminal.

  • Patent number: 6154532
    Abstract: A device and method minimize telephone charges by not answering the destination telephone when an incoming call is detected. Preconnection information such as dialed number identification system (DNIS) information, phone type information digits, and automatic number identification (ANI) information is automatically provided by the public switched telephone network to the destination telephone in response to the incoming call. The preconnection information is examined to determine if the rate structure is such that it would be more desirable to have the call billed as if it originated from the destination telephone or from the source telephone. If it is less expensive to have the call originate from the source telephone, the call is answered. If it is less expensive to have the call originate from the destination phone, a signal is sent to the user prompting them to hang up. When the caller hangs up, a return call is placed to the number and the caller answers.

  • Patent number: 6016344
    Abstract: A system D interfaces with a multiplicity of individual terminals T1-Tn of a telephone network facility C, at the terminals callers are prompted by voice-generated instructions to provide digital data that is identified for positive association with a caller and is stored for processing. The caller's identification data is confirmed using various techniques and callers may be ranked and accounted for on the basis of entitlement, sequence or demographics. Callers are assigned random designations that are stored along with statistical and identification data. A break-off control circuit may terminate the computer interface aborting to a terminal for direct communication with an operator. Real-time operation processing is an alternative to stored data. The accumulation of stored data (statistical, calling order sequence, etc.) is variously processed and correlated as with developed or established data to isolate a select group or subset of callers who can be readily identified and reliably confirmed.

  • Patent number: 5905791
    Abstract: An interexchange carrier (IXC) switch and an associated database route qualified calls dialed to local service provider (LSP) subscribers onto interconnecting facilitiies with local access settlement rates, thereby allowing a local rather than toll cost structure. The IXC switch and associated database operate with existing toll features including those features which translate a private dialed number into a public number. The IXC switch and associated database classify the call into a jurisdictional classification from a customer billing and feature application perspective, and from a routing perspective independent of the customer billing and feature application classification. The jurisdictional classification can include, example, local, toll, interLATA toll or intraLATA toll.

  • Patent number: 5883948
    Abstract: A method for automatically updating a central local number portability (LNP) database shared among a plurality of central office switches is instigated when a message from a provisioning system to add a directory number is received by a central office switch. In response to the message, a first central office switch accesses the central LNP database by sending a query message which contains the directory number to be added and routing data specific to the central office switch. Responsive to the query message, the LNP database searches for the directory number received from the first central office switch. If the directory number is found, the database queries a second central office switch to determine if the directory number is in use. If the number is in use, the central LNP database returns a failure message to the first central office switch.

  • Patent number: 5878123
    Abstract: A telephone system and method that enables a telephone to handle more call appearances that it has call appearance keys. The telephone system contains a display and general purpose keys that are used to respond to prompts shown on the display. When the telephone system receives an incoming call that is not assigned to a dedicated call appearance key, then the system places a prompt on the display. The prompt identifies the line upon which the telephone call is received by placing an identifying name, number or telephone location on the display. The prompt is placed adjacent to one of the general purpose keys so that the prompt is clearly associated with only one of the general purpose keys. The system then assigns that general purpose key to the telephone line addressed by the prompt. As a result, the general purpose key becomes a call appearance key and a person using the telephone system can complete a connection between that telephone an incoming call by pressing that general purpose key.

  • Patent number: 5875241
    Abstract: An information processing system adapted for use in conjunction with a telephone communication system. The information processing system includes a caller identification signal receiver, a timed switching device, and a call forwarding device. When no incoming call is being received, the timed switching device is in a first, open state, such that a circuit between the telephone line and the call forwarding device is interrupted. Upon receipt of an incoming call on the telephone line, the timed switching device and the caller identification signal receiver are activated. The timed switching device enters a second, closed state after a finite amount of time has elapsed such as, for example, several seconds, thereby allowing sufficient time for the caller identification signal to arrive on the incoming telephone line.
