Method and system for informing callers within a queue

## Abstract

A system for implementing a technique for operatively integrating an automatic call distributor and an interactive voice response unit is disclosed. Upon receiving and storing an interaction input from a caller seeking information, the automatic call distributor determines the availability of an agent workstation to respond to the interaction input. The interactive voice response unit provides the caller with access to the information when the automatic call distributor determines an agent workstation is unavailable to respond to the interaction input. The automatic call distributor transmits the interaction input to an appropriate agent workstation whenever that particular agent workstation becomes available to respond to the interaction input.

## Background
REFERENCE TO RELATED APPLICATIONS
Benefit is claimed under 35 U.S.C. § 119(e) based on U.S. Provisional Patent Application No. 60/143,460, filed Jul. 13, 1999, and U.S. Provisional Patent Application No. 60/186,190, filed Mar. 1, 2000, which are each hereby incorporated by reference.


BACKGROUND
The present invention generally relates to techniques for providing a caller with information relevant to the caller's call while the call is within a queue, and more particularly, but not exclusively, relates to methods and systems for allowing a caller to access information about products, services, and the like while the call is stored within the queue.
In a call center, a call center agent typically communicates with customers through inbound calls, out-bound calls, or both. This communication is often by voice using a telephone handset or headset component of the agent's workstation. Usually, the workstation also includes a computer terminal or personal computer to interface with various application modules. These modules provide the agent information directed to the particular customer service involved. In one common application, a customer's account information is provided on a display viewable by the agent.
The time it takes agents to handle calls and the lapse of time between calls are factors that influence the efficiency of call center operations. Although sometimes at odds with efficiency goals, it is also generally desirable to provide customers as favorable an impression as possible with regard to call center transactions. To manage such competing interests, there is a continuing demand for further advancements in the call center technology area.
SUMMARY
One form of the present invention is a unique technique for a providing a caller with access to information related to the caller's call while the call is stored within a queue whereby the caller may receive pertinent information prior to the call being removed from the queue. Another form of the present invention is a unique system operable to provide a caller with access to information related to the caller's call while the call is stored within a queue whereby the caller may receive pertinent information prior to the call being removed from the queue. In yet another form of the present invention is a unique telephony server for operatively integrating an automatic call distributor queue and an interactive voice response unit in response to an interaction input whereby the telephony server's capacity to handle incoming calls is increased.

In one common arrangement, one workstation is designated for an agent supervisor that has different capabilities than those of other workstations. Furthermore, it should be understood that more or fewer workstations may be utilized than those illustrated.
CT server 40 incorporates a unique technique of the present invention whereby ACD queue 44 and IVR 46 are operatively integrated to enable callers having calls stored within ACD queue 44 to navigate menus while the risk of the calls being removed from ACD queue 44. One embodiment of the technique is ACD/IVR integration procedure 70 shown in FIG. 2. An increased capacity of CT server 40 in handling incoming calls will be clear to those skilled in the art of the present invention with the following description of procedure 70. Referring additionally to FIG. 2, an interaction input from a caller is received by CT server 40 prior to an implementation of procedure 70 by CT server 40. The interaction input can be in the form of a telephone call originating from telephone 24, or in the form of a chat call originating from computer 26. In either case, the caller is typically seeking information relating to a product for sale by call center 30, a service performed by call center 30, a company profile of call center 30, etc. An implementation of procedure 70 by CT server 40 provides access to the caller of such information while the interaction input is stored within ACD queue 44 whereby the caller may search for information pertinent to the call prior to the interaction input being removed from ACD queue 44 and transmitted to an appropriate agent workstation 60. Thus, while awaiting connection to an agent workstation 60, the caller is presented within an opportunity to receive information pertinent to the call and to thereafter terminate the call. As such, an agent workstation 60 would not have to respond to the interaction input if the caller terminated the call after receiving the pertinent information.
CT server 40 will initiate and continually implement procedure 70 in response to an initial and continual reception of the interaction input. Thus, upon a termination of a reception of the interaction input, CT server 40 immediately ceases an implementation of procedure 70 regardless of which stage or stages of procedure 70 CT server 40 is actively employing. Upon an initial reception of an interaction input, CT server 40 places the interaction input into ACD queue 44 during stage S72 of procedure 70. Upon completion of stage S72, CT server 40 directs IVR 46 during stage S74 to provide a message to the caller of the interaction input. In one embodiment, the message includes a greeting for the caller and an estimated holding period of the interaction input within ACD queue 44.
While the message is being provided to the caller during stage S74, ACD queue 44 is executing a queue management routine as would occur to those skilled in the art for routing the interaction input from ACD queue 44 to an available agent workstation 60. The output of the queue management routine is tested during stage S76 of procedure 70. If the output of the queue management routine initially indicates that an agent workstation 60 is available to respond to the interaction input, CT server 40 proceeds to stage S82 wherein the interaction input is transmitted to the appropriate agent workstation 60 and procedure 70 is thereafter terminated. If the output of the queue management routine initially indicates that none of the agent workstations 60 is available to respond to the interaction input, then CT server 40 proceeds to execute a database access routine 90 during stage S78 of procedure 70.
Referring additionally to FIG. 3, CT server 40 is operable to provide information to the caller from either one or more databases (not shown) of call center 30 and/or handlers of CT server 40 in response to one or more selection inputs from the caller. To his end, during stage S92 of routine 90, IVR 46 provides a menu to the caller whereby the caller can navigate the menu in order to obtain any sough after information from the databases. The menu is audibly transmitted to telephone 24 if the interaction input originated from telephone 24, and is displayed on computer 26 if the interaction input originated from computer 26. Thereafter, CT server 40 awaits a reception of a selection input from the caller during stage S94.
Upon reception of a selection input, CT server 40 proceeds to stage S96 wherein either CT server 40 provides information corresponding to the selection input and/or IVR 46 provides an additional menu corresponding to the selection input. In either case, CT server 40 then proceeds to stage S94 to await a reception of another selection input. CT server 40 will thereafter continually execute stage S94 and/or stage S96 until one of two events occur. The first event is an indication by ACD 44 queue that one or more agent workstations 60 are available to respond to the interaction input. CT server 40 will then proceed to stage S80 to terminate the execution of routine 90 and to stage S82 to transmit the interaction input to an appropriate workstation 60. Upon completion of stage S80 and stage S82, CT server 40 terminates an implementation of procedure 70.
The second event is a termination of a transmission of the interaction input from the caller, e.g. the caller hangs up telephone 24, or the caller closes a program on computer 26. For this event, CT server 40 immediately terminates an implementation of procedure 70 regardless of which stage or stages of procedure 70 currently being employed by CT server 40. However, prior to the caller's termination of the interaction input, the caller was presented with an opportunity to receive sought after information without the risk of the interaction input being removed from ACD queue 44. Thus, call center 30 becomes more efficient as a function of the number of callers receiving information pertinent to their calls without having to communicate with an agent workstation 60.
Referring to FIG. 1, an enterprise system as an alternative embodiment of the present invention comprises CT server 40, telecommunication switch 42, and conventional components as would occur to those skilled in the art. Additionally, a service providing system as an alternative embodiment of the present invention comprises CT server 40, telecommunication switch 42, and conventional components as would occur to those skilled in the art. Both the enterprise system embodiment and the service providing system embodiment implement the principles of the present invention.
