Abstract: System and method for monitoring calls parked on one or more automatic call distributors (ACDs). Calls parked on an ACD are monitored through the use of a call park server that maintains a relational database. The relational database includes a call-leg information table and a method table. The call-leg information table is used to track and maintain the status of each call-leg parked on an ACD. The method table includes pre-determined methods that can be executed in response to a change in status of the parked call-legs. The method table provides a suite of methods that can be selected by a parking facility, for example, an automated response unit or an operator console, to be applied to the parked call-leg when particular events occur.

Abstract: A mobile telephone, or personal communication services subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As known in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g., providing further directory assistance).

Abstract: The automated customer service system maintains and uses a list of available resources, such as an agent qualification profile, in conjunction with a customer sensitivity profile, to automatically assign available resources, such as agents, to the various campaigns. The agent qualification profile identifies any special skills or qualifications that an agent may possess, such as language skills, type of voice, efficiency, and type of call processing skills. The customer sensitivity profile contains information regarding the manner, time and date, and location for contact which are preferred by the customer. The system administrator devises a strategy script based upon the customer sensitivity requirements and the agent qualifications. The strategy script determines which resources, such as agents, meet which requirements, and whether there are adequate resources to handle the requirements of concurrent campaigns.

Abstract: A telephone call-routing system comprises a routing intelligence adapted to receive real-time activity reports on busy status of remote telephone stations, and to route incoming calls based on the busy status. In a preferred embodiment the routing intelligence sets a busy semaphore for each station to which a call is routed at the time the call is routed, before a real-time signal is returned that the station is in fact busy. The semaphore is initially set to busy for a first period of time substantially equal to the known latency for returning the real-time busy signal. After the first period of time, and with return of a real-time busy signal, the semaphore is reset to busy for a second period of time substantially equal to the historical average elapsed time for calls in the call-routing system, after which the semaphore is released. After the first period of time, and in the absence of the real-time busy signal, the semaphore is immediately released so further calls may be routed to the station.

The call referral system includes a routing monitor computer (40) coupled with the switch for monitoring the connection of the calls to the called party. The monitoring computer receives and stores a gate size selected by the called party indicating the maximum number of calls the called party wishes to simultaneously handle through each of its gates. The gates are comprised of single destination telephone numbers or groups of destination telephone numbers to the various destinations (17 & 18, 32).

Abstract: A PBX/automatic call distributor (ACD) system allows callers to exercise control over their rank order within a phone queue. The ACD accesses a call database and develops offers to be made to callers, based upon a caller reaching a particular position in a queue or at a position at which the call is first placed in the queue. An interactive voice response unit (IVRU) is employed to offer a caller a chance to move up in the queue in return for a payment. If the caller wishes to accept the offer, the caller responds by using the touch tone keys of his/her telephone and entering a credit card number, an account number, or indicating some other method of payment. The ACD then changes the rank order of the caller's call within the phone queue and alters the rank position of other calls within the queue, accordingly.

Abstract: In an ACDQ (Automatic Call Distribution Queuing) call transfer method, when an incoming ACDQ call takes place in a telephone set group for exclusively handling ACDQ calls in an ACDQ group which is set by a plurality of telephone sets connected to a plurality of switching centers, it is determined whether all the telephone sets belonging to the telephone set group are busy. The ACDQ call is transferred to the same telephone set group connected to a switching center of a transfer destination which forms the same ACDQ group when all the telephone sets belonging to the telephone set group are busy. Ghost calls as virtual call sounds are originated from the switching center of the transfer destination to at least idle telephone sets in the same telephone set group. The actual ACDQ call is transferred to a telephone set which responds to the originated ghost call first. The ghost calls to remaining telephone sets are released.

Abstract: A method for a reporting application to flexibly report the status of an entity in a call center to a requesting application is provided. The entity could be in one or more states. Examples of an entity are a directory number, an agent, a group, a routing point, and an agent place. The requesting application sets the priority of these states belonging to the entity by sending a status priority table to the reporting application. The reporting application reports the status based on the active states of the entity and the priority table. As an example, the reported status could be the active state having the highest priority in the table. This state is reported back to the requesting application. Because different requesting applications could present different priority tables, the reporting application could report different states for the same entity.

A routing processing system is operatively associated with the call manager and in response to a routing request uses a stored routing algorithm for selecting one of the subscriber resources to receive the call. The routing processing system transmits a request to the selected subscriber resource for acceptance of the call.

Abstract: Call pacing method in which agent availability and call answers are based on probability statistics and the allowable maximum abandon rate. A weight is assigned each agent engaged in a call or in after-call work. This weight is a function of how long an agent has been engaged in a call or in after-call work, the duration of a time window for which a prediction that the agent will be free is made, and the maximum allowable abandon call rate. The sum of the weights is the predicted number of engaged agents that will become free. The time window is independent of the interval between the dial of a call and when the call is expected to be answered and is automatically adjusted by the system; lengthened when the abandon call ratio falls below the acceptable ratio and shortened when the ratio rises above the acceptable ratio.

Abstract: A system for routing calls has a plurality of call centers and a central controller for managing activity of the plurality of call centers, including call loading. The central controller utilizes a method for managing loading based on estimates of loading for call centers in the system for which real time loading information is not available during certain time intervals. The method involves retrieving a previous status of the call center for which real time information is not available, and using that previous status to perform and estimate of current loading for management purposes.

Abstract: A call recording system and method records telephone calls routed by a telephonic switch 104 to agents located at computer terminals 108.

Abstract: An apparatus and method are provided for identifying a call record of a telephone call received from a PSTN and overflowed from a source automatic call distributor to a destination automatic call distributor, the call record having been stored under a call identifier of the source automatic call distributor in a memory of a host computer serving both the source automatic call distributor and the destination automatic call distributor. The method includes the step of storing a call action provided message in a call overflow table of the host computer including a call identifier assigned by the source automatic call distributor and an identifier of the source automatic call distributor. An overflow request is transferred over an ISDN facility to the destination automatic call distributor including the call identifier.

Abstract: A technique is provided for establishing data communications links and associated telephone calls between customers and customer service representatives. Customers access the Internet from clients. A merchant provides an on-line catalog using a Web server. When the customer requests that a customer service representative contact the customer, linking information is provided to the client. When one of the customer service representatives is available, the server sends a notification packet to the client to notify the customer and to provide the customer with an opportunity to decide whether or not to continue. If the customer decides to continue, an Internet communications link and telephone call are established between the customer and the customer service representative based on the linking information.

Abstract: A "look-ahead" calculation projects what would be the effect on the abandon rate if several additional abandons happened to occur. The method uses the result of this "look-ahead" calculation of a projected abandon rate to modify its estimation of the number of ringing dials that will or will not result in an answer. If the projected abandon rate indicates the abandon rate is sensitive to an increase in the number of abandons, the method increases the estimate of those ringing calls which are likely to answer by up to two and one-half times the "average", depending on the degree of sensitivity. If the sensitivity forecasts little danger of exceeding the set abandon rate, the method decreases the estimate of ringing calls that will answer by up to one-half. In the former case, dialing is slowed down and in the latter, dialing is speeded up. Both cases have the advantage to "looking ahead" rather than simply reacting to events that may not be quickly correctable once they have occurred.

Abstract: The maximum wait time for callers in a call center (FIG. 10) is lowered by selecting, for an agent (25) who has just become available to handle a call, a highest-priority waiting call that would most likely wait the longest if it were not selected at this time. Anticipated wait times are computed for the calls at the heads of the non-empty highest-priority call queues that correspond to the agent's skills or splits (202-210). The anticipated wait time of a call is computed as the call's present (elapsed) wait time plus the average rate of advance of calls in the call's queue (210). The call with the longest anticipated wait time is then selected first and is assigned to the available agent for handling (212-216). The process is repeated each time that any agent becomes available.

Abstract: A method, which may be carried through a computer and its modem, is used to minimize the telephone time necessary to establish direct voice contact with the computer technician or other service provider and to provide information to the technician about the computer system and program. When contact is made through the modem with the information provider's PBX, the caller's computer would send a signal, indicating whether this is a reconnect or a new contact. If the customer support telephone line is for a number of programs or if there are different queues for different problems, a dialog box can be used to supply the necessary information to select the appropriate queue. The telephone system would provide an indication of the current wait time for the particular product or problem taking into account not only the open lines currently in the queue, but other callers who will be calling back at an appropriate time.

Abstract: An agent vector monitors selected performance parameters of a call center, such as service times, in-queue times, call volumes, call abandonment rates, benefits derived from having different agents handle calls requiring different skills, proportions of work spent by agents on handling calls requiring different skills, etc., and automatically adjusts agents' call-handling assignments, for example, by changing the skills to which an agent is assigned or by changing the relative priorities of the agent's skills, in order to optimize a predefined objective. The objective is a selected performance characteristic of the call center, for example, the total benefit to the call center of individual ones of the agents handling calls requiring individual agent skills.

Abstract: A system and method for selectively adjusting the caller identification of a calling party based, in party, on parameters associated with adjusting the calling party. Security codes can be used in conjunction with a database to insure that the substituted ID is legitimate. The one embodiment or network based predictive dialer is used to place calls for agents geographically separated from both the network and other agents. The network system instigates a calling campaign where remote agents are connected through the network to called parties where the called party receives the caller ID information pertaining to the calling campaign and not the caller ID of the agent.

Abstract: An apparatus and method are provided for identifying a call record of a telephone call to be overflowed from a source automatic call distributor to a destination automatic call distributor. The call record is of a type having been previously stored under a call identifier of the source automatic call distributor in a memory of the host computer serving both the source automatic call distributor and destination automatic call distributor in an area of the memory reserved for the source automatic call distributor. The method includes the step of storing a call action provided message in a call overflow table of the host computer including the call identifier of the telephone call and an identifier of the source automatic call distributor.

Abstract: A call center, including a PBX/ACD and a CTI server, is provided to route both voice and video calls to a single group of agents. A modem call from an end-point terminal is used to initiate and prepare a video call. Upon receiving an inbound voice or a modem call, the PBX/ACD passes ANI and DNIS to the CTI server. In response to the inbound voice or video call, the CTI server selects a group of agents capable of handling the inbound call, and sends routing information to the PBX/ACD so that the ACD can route the inbound call to the selected group of agents. Before an inbound call is routed to an agent, the CTI server generates a flag to indicate the nature of the inbound call. If the flag indicates a video call initiated by a modem call, a modem at the agent's side will respond to the modem call from the end-point terminal, and a separate ISDN call is then made to establish a video connection. If the flag indicates a voice call, a telephone set at the agent's side will simply ring.

Abstract: A group conferencing arrangement for a counseling service permits the simultaneous connection of two or more service representatives to a call-in caller, i.e. without need for one service representative to add-on the second service representative conferee.

Abstract: Enhanced voice services (EVS) interactively communicate with a caller so as to provide audio prompting and selection of the final termination of a call. The present improvement includes load balancing, wherein degraded service of audio response units (ARUs) is detected. With load balancing, individual EVS ARU nodes are lumped into groups, where a group is a set of two or more functionally identical EVS audio response units (ARUs) that all support the same EVS customer applications. An inbound call for a given EVS application can be routed, based on a lookup at the data access point (DAP), to any ARU in the group. With the operating level of each ARU in a particular group being known, the percent allocations for each ARU are determined and an update is made at the DAP to route incoming calls to each ARU in the group according to the specified percentages.

Abstract: A customer queuing system receives telephone calls on one port of a switching system for handling by servers attached to output ports of the switching system.

Abstract: A method of controlling silent monitoring of a group in an electronic exchange accommodating a terminal of a monitoring individual and terminals of individuals to be monitored, wherein a call between a prescribed individual to be monitored and a customer is allowed to be monitored by the monitoring individual. The individuals to be monitored are divided into groups, groups to be monitored are allocated to the monitoring individual and this information is entered into a call controller of the electronic exchange. The call controller observes, group by group, call-in-progress/call-not-in-progress status of the individuals to be monitored and allows the monitoring individual to automatically monitor, in succession, calls between customers and call-in-progress individuals to be monitored belonging to the monitoring target groups allocated to the monitoring individual.

Abstract: The method relates to a group (G) of agent communication terminal apparatus (AKE) that are distributed over several communication systems (KS1, 2) of a communication network. If, given an incoming call (ar) in a communication system (KS1), no allocated agent communication terminal apparatus (AKE) is still free for the respective group (G), a resource request (ra) is transmitted to communication systems (KS2) to which agent communication terminal apparatus (AKE) of the same group (G) are connected. Using a response (aw), the addressed communication systems (KS2) indicate whether one of the agent communication terminal apparatus (AKE) is free or whether they are all occupied. After the signaling of a free agent communication terminal apparatus (AKE), the incoming call (ar) is switched to the respective communication system (KS2).

Abstract: A call-distribution function (150) of an ACD system (101) improves the equity of distribution of calls to agents (106-108) by basing the distribution on the agents' individual occupancies. Illustratively, determining an agent's occupancy involves either determining (304) how many calls the agent has handled within a predetermined time interval, or determining (305) how much time of a predetermined time interval the agent has spent on handling of calls. The occupancy is periodically re-determined, and a next call is allocated to the presently least-occupied one of agents who are available to take the call, or to an agent to whose occupancy the allocation will be most beneficial, such as an available agent to whom allocation of the call will maximize convergence of actual and target occupancies.
