The disclosure relates to the field of contact center technology, specifically to the field of cloud-implemented automated callback systems.
Large volumes of caller traffic at a contact center may cause long queues of callback requests. While callback queues reduce the burden on callers by not requiring them to wait on hold, callback queues present other problems such as failed callback dialing attempts, unanswered callbacks, and dropped calls during callbacks. These problems may increase the time between successful callback attempts, Which can be a burden on contact center resources.
One existing solution to the burden caused by repeated callbacks is the use of alternate contact sites from which callback attempts can be made. Using alternate contact sites to make callback attempts can potentially increase the number of callback attempts possible without burdening the primary contact center site. However, routing inefficiencies may cause alternate contact sites to go underutilized, reducing their effectiveness. Further, routing of callbacks to alternate contact sites does not solve the problems inherent in use of callback queues. Callback problems such as those noted above (failed callback dialing attempts, unanswered callbacks, dropped calls, etc.) may cause the caller to be placed back into the callback queue at the alternate contact site in the same manner as at the primary contact center. Further, routing to alternate contact sites may cause discontinuity in caller/agent relations in cases where there have been previous contacts between a particular caller and a particular agent.
What is needed is a system and method for optimizing callback times to increase the success rate of callbacks while managing overflow of calls to alternate sites when callbacks are unsuccessful.
Accordingly, the inventor has conceived and reduced to practice, a system and method for optimizing callback times to increase the success rate of callbacks while managing overflow of calls to alternate sites when callbacks are unsuccessful. The system and method use a pacing algorithm to determine when callbacks are likely to be successful from a preferred contact site, routing to alternate callback sites when callbacks are unsuccessful, and preferences for re-routing back to the preferred site when a callback is successful and the agent with whom the caller has interacted previously is available.
According to a preferred embodiment, a system for callback management with alternate site routing and callback pacing is disclosed, comprising: a callback cloud service comprising a first computing device comprising a memory and a processor, and a first plurality of programming instructions stored in the memory and operating on the processor of the first computing deice, which causes the first computing device to: communicate with an on-premise callback system; maintain relevant agent and client data from an on-premise callback system interface with one or more alternate sites comprising of an on-premise callback system; execute callback fulfillment requests; an on-premise callback system operating at a preferred contact site comprising a second computing device comprising a memory and a processor, and a second plurality of programming instructions stored in the memory and operating on the processor of the second computing device, which causes the second computing device to: communicate with a callback cloud service; send data related to callback objects and agents to a callback cloud service; receive a call to an agent from a caller; create a callback object upon the caller's request for a callback; receive a callback time from a pacing algorithm; and execute a callback to the caller at the callback time; and a pacing algorithm comprising a third plurality of programming instructions stored in the memory and operating on the processor of the second computing device, which causes the second computing device to: receive the callback objects from the callback cloud service; determine times when the caller and the agent are both likely to be available; predict a likelihood that the caller will answer at each determined time; select the callback time from the determined times with the greatest predicted likelihood; and send the callback time to the on-premise callback system.
According to another preferred embodiment, a method for callback management with alternate site routing and callback pacing is disclosed, comprising the steps of: communicating with an on-premise callback system using a callback cloud service operating on a first computing device; maintaining relevant agent and client data from the on-premise callback system using the callback cloud service; interfacing with one or more alternate sites comprising of an on-premise callback system using the callback cloud service; executing callback fulfillment requests using the callback cloud service; sending data related to callback Objects and agents to a callback cloud service using an on-premise callback system operating on a second computing device; receiving a call to an agent from a caller using the on-premise callback system; creating a callback object upon the caller's request for a callback using the on-premise callback system; receiving a callback time from a pacing algorithm using the on-premise callback system; executing a callback to the caller at the callback time using the on-premise callback system; receiving the callback objects from the callback cloud service using a pacing algorithm operating on the second computing device; determining times when the caller and the agent are both likely to be available using the pacing algorithm; predicting a likelihood that the caller will answer at each determined time using the pacing algorithm; selecting the callback time from the determined times with the greatest predicted likelihood using the pacing algorithm; and sending the callback time to the on-premise callback system.
According to an aspect of an embodiment, the pacing algorithm further: determines a callback attempt limit; increments a counter each time a failed callback is made to the caller; and upon reaching callback attempt limit, routes remaining callback attempts to an alternate contact site.
According to an aspect of an embodiment, a second on-premise callback system operating at an alternate contact site, is used to: receive the routing from the pacing algorithm; determine a callback time; immediately prior to the callback dim determine whether a preferred agent at the preferred callback site is available; if the preferred agent is available, route the callback to the preferred contact site for execution; and if the preferred agent is not available, execute the callback to the caller from the alternate contact site.
The accompanying drawings illustrate several aspects and, together with the description, serve to explain the principles of the invention according to the aspects. It will be appreciated b one skilled in the art that the particular arrangements illustrated in the drawings are merely exemplary, and are not to be considered as limiting of the scope of the invention or the claims herein in any way.
The inventor has conceived, and reduced to practice, a system and method for optimizing callback dines to increase the success rate of callbacks while managing overflow of calls to alternate sites when callbacks are unsuccessful. The system and method use a pacing algorithm to determine when callbacks are likely to be successful from a preferred contact site, routing to alternate callback sites when callbacks are unsuccessful, and preferences for re-routing back to the preferred site when a callback is successful and the agent with whom the caller has interacted previously is available.
Large volumes of caller traffic at a contact center may cause long queues of callback requests, While callback queues reduce the burden on callers by not requiring them to wait on hold, callback queues present other problems such as failed callback dialing attempts, unanswered callbacks, and dropped calls during callbacks. These problems may increase the time between successful callback attempts, which can be a burden on contact center resources.
One existing solution to the burden caused by repeated callbacks is the use of alternate contact sites from which callback attempts can be made. Using alternate contact sites to make callback attempts can potentially increase the number of callback attempts possible without burdening the primary contact center site. However, routing inefficiencies may cause alternate contact sites to go underutilized, reducing their effectiveness. Further, routing of callbacks to alternate contact sites does not solve the problems inherent in use of callback queues. Callback problems such as those noted above (failed callback dialing attempts, unanswered callbacks, dropped calls, etc.) may cause the caller to be placed back into the callback queue at the alternate contact site in the same manner as at the primary contact center.
Further, routing to alternate contact sites may cause discontinuity in caller/agent relations in cases where there have been previous contacts between a particular caller and a particular agent. To solve this problem of caller/agent relationship discontinuity, an previous interactions between a particular caller and a particular agent may be tracked. When a call is routed to an alternate contact site for further callback attempts, a successful callback attempt to the particular caller may trigger a secondary check for the availability of the particular agent. If the agent is immediately available, the call may be routed back to the particular agent at the preferred contact site instead of being handled by an agent at the alternate callback site. If the agent will be available shortly, the caller may be notified that the particularly agent with whom he or she has interacted will be available shortly, and may be given the opportunity) wait on hold until that particular agent is available. If the agent is not available or the caller has decided riot to wait for that particular agent, the call can be handled by an agent at the alternate contact site.

Definitions
“Callback” as used herein refers to an instance of an individual being contacted after their initial contact was unsuccessful. For instance, if a first user calls a second user on a telephone, but the second user does not receive their call for one of numerous reasons including turning off their phone or simply not picking up, the second user may then place a callback to the first user once they realize they missed their call. This callback concept applies equally to many forms of interaction that need not be restricted to telephone calls, for example including (but not limited to) voice calls over a telephone line, video calls over a network connection, or live text-based chat such as web chat or short message service (SMS) texting. While a callback (and various associated components, methods, and operations taught herein) may also be used with an email communication despite the inherently asynchronous nature of email (participants may read and reply to emails at any time, and need not be interacting at the same time or while other participants are online or available), the preferred usage as taught herein refers to synchronous communication (that is, communication where participants are interacting at the same time, as with a phone call or chat conversation).
“Callback object” as used herein means a data object representing callback data, such the identities and call information for a first and second user, the parameters for a callback including what time it shall be performed, and any other relevant data for a callback to be completed based on the data held by the callback object.
“Latency period” as used herein refers to the period of Time between when a Callback Object is created and the desired Callback is initiated, for example, if a callback object is created and scheduled for a time five hours from the creation of the object, and the callback initiates on-time in five hours, the latency period is equal to the five hours between the callback object creation and the callback initiation.
“Brand” as used herein means a possible third-party service or device that may hold a specific identity, such as a specific MAC address, IP address, a username or secret key which can be sent to a cloud callback system for identification, or other manner of identifiable device or service that may connect with the system. Connected systems or services may include a Private Branch Exchange (“PBX”), call router, chat server which may include text or voice chat data, a Customer Relationship Management (“CRM”) server, an Automatic Call Distributor (“ACD”), or a Session Initiation Protocol (“SIP”) server.
“Fulfill” as used herein means to execute a callback call from an agent to a client, without unexpected drops of the line of communication, and without the client requesting or being assigned to a queue.
“Agent” as used herein is a person which is at a location which contains an on-premise callback system.
“Client” as used herein means a person which is on the receiving end of callback call from an agent, and may also refer to the person which initiated the line of communication with a brand or agent.
“Preferred site” as used herein means the initial contact site which routed the callback request to a queue.
Conceptual Architecture
A PSTN 203 or the Internet 202 (and it should be noted that not all alternate connections are shown for the sake of simplicity, for example a desktop PC 226 may communicate via the Internet 202) may be further connected to a plurality of enterprise endpoints 220, which may comprise cellular telephones 221, telephony switch 222, desktop environment 225, internal Local Area Network (LAN) or Wide-Area Network (WAN) 230 and mobile devices such as tablet computing device 228. As illustrated, desktop environment 225 may include both a telephone 227 and a desktop computer 226, which may be used as a network bridge to connect a telephony switch 222 to an internal LAN or WAN 230, such that additional mobile devices such as tablet PC 228 may utilize switch 222 to communicate with PSTN 202. Telephone 227 may be connected to switch 222 or it may be connected directly to PSTN 202. It will be appreciated that the illustrated arrangement is exemplary, and a variety of arrangements that may comprise additional devices known in the art are possible, according to the invention.
Callback cloud 201 may respond to requests 240 received from communications networks with callbacks appropriate to the technology utilized by such networks, such as data or Voice over Internet Protocol (VOIP) callbacks 245, 247 sent to Internet 202, or time-division multiplexing (TDM) such as is commonly used in cellular telephony networks such as the Global System for Mobile Communications (GSM) cellular network commonly used worldwide, or VOIP callbacks to PSTN 203. Data callbacks 247 may be performed over a variety of Internet-enabled communications technologies, such as via e-mail messages, application pop-ups, or Internet Relay Chat (IRC) conversations, and it will be appreciated by one having ordinary skill in the art that a wide variety of such communications technologies are available and may be utilized according to the invention. VOIP callbacks may be made using either, or both, traditional telephony networks such as PSTN 203 or over VOIP networks such as Internet 202, due to the flexibility to the technology involved and the design of such networks. It will be appreciated that such callback methods are exemplary, and that callbacks may be tailored to available communications technologies according to the invention.
A profile manager 250 associated with a callback cloud 201 may receive initial requests to connect to the callback cloud 201, and forward relevant user profile information to a callback manager 270, which may timber request environmental context data from an environment analyzer 260. Environmental context data may include (for example, and not limited to) recorded information about when a callback requester or callback recipient may be suspected to be driving or commuting from work, for example, and may be parsed from online profiles or online textual data.
The callback manager 270 centrally manages all callback data, creating a callback object which be used to manage the data for a particular callback, and communicates with an interaction manager 280 which handles requests to make calls and bridge calls, which go out to a media server 290 which actually makes the calls as requested. In this way, the media server 290 may be altered in the manner in which it makes and bridges calls when directed, but the callback manager 270 does not need to adjust itself, clue to going through an intermediary component, the interaction manager 280, as an interface between the two. A media server 290, when directed, may place calls and send messages, emails, or connect voice over IP (“VoIP”) calls and video calls, to users over a PSTN 203 or the Internet 202. Callback manager 270 may work with a user's profile as managed by a profile manager 250, with environmental context horn an environment analyzer 260 as well as (if provided) EWT information for any callback recipients (for example, contact center agents with the appropriate skills to address the callback requestor's needs, or online tech support agents to respond to chat requests), to determine an appropriate callback time for the two users (a callback requestor and a callback recipient), interfacing with an interaction manager 280 to physically place and bridge the calls with a media server 290. If a callback is requested, a callback cloud 201 may find an optimal time to bridge a call between the callback requestor and callback recipient, as necessary.
Additionally, callback cloud 201 may receive estimated wait time (EWT) information from an enterprise 220 such as a contact center. This information may be used to estimate the wait time for a caller before reaching an agent (or other destination, such as an automated billing system), and determine whether to offer a callback proactively before the customer has waited for long. EWT information may also be used to select options for a callback being offered, for example to determine availability windows where a customer's callback is most likely to be fulfilled (based on anticipated agent availability at that time), or to offer the customer a callback from another department or location that may have different availability. This enables more detailed and relevant callback offerings by incorporating live performance data from an enterprise, and proves customer satisfaction by saving additional time preselected recommendations and proactively-offered callbacks.
When a user calls from a mobile device 212 or uses some communication application such as (for example, including but not limited to) SKYPE™ or instant messaging, which may also be available on a laptop or other network endpoint 660, 670 other than a cellular phone 212, they may be forwarded to brands 310 operated by a business in the manner described herein. For example, a cellular phone call my be placed over PSTN 203 before being handled by a call router 314 and generating a session with a SIP server 312, the SIP server creating a session with a callback cloud 320 with a profile manager 321 if the call cannot be completed, resulting in a callback being required. A profile manager 321 in a callback cloud 320 receives initial requests to connect to callback cloud 320, and forwards relevant, user profile information to a callback manager 323, which may further request environmental context data from an environment analyzer 322. Environmental context data may include (for example, and not limited to) recorded information about when a callback requester or callback recipient may be suspected to be driving or commuting from work, for example, and may be parsed from online profiles or online textual data, using an environment analyzer 322.
A callback manager 323 centrally manages all callback data, creating a callback object which may be used to manage the data for a particular callback, and communicates with an interaction manager 324 which handles requests to make calls and bridge calls, which go out to a media server 325 which actually makes the calls as requested. In this way, the media server 325 may be altered in the manner in which it makes and bridges calls when directed, but the callback manager 323 does not need to adjust itself, due to going through an intermediary component, the interaction manager 324, as an interface between the two. A media server 325, when directed, may place calls and send messages, ernails, or connect voice over IP (“VoIP”) calls and video calls, to users over a PSTN 203 or the Internet 202. Callback manager 323 may work with a user's profile as managed by a profile manager 321, with environmental context from an environment analyzer 322 as well as (if provided) EWT information for any callback recipients (for example, contact center agents with the appropriate skills to address the callback requestor's needs, or online tech support agents to respond to chat requests), to determine an appropriate callback time for the two users (a callback requestor and a callback recipient), interfacing with an interaction manager 324 to physically place and bridge the calls with a media server 325. In this way, a user may communicate with another user on a PBX system 311, or with automated services hosted on a chat server 315, and if they do not successfully place their call or need to be called back by a system, a callback. cloud 320 may find an optimal time to bridge a call between the callback requestor and callback recipient, as necessary.
Present in this embodiment is a brand interface server 430, which may expose the ide of, and any relevant API's or functionality for, any of a plurality of connected brands 410, to elements in a callback cloud 420. In this way, elements of a callback cloud 420 may be able to connect to, and interact more directly with, systems and applications operating in a business' infrastructure such as a SIP server 412, which may be interfaced with a profile manager 421 to determine the exact nature of a user's profiles, sessions, and interactions in the system for added precision regarding their possible availability and most importantly, their identity. Also present in this embodiment is an intent analyzer 440, which analyzes spoken words or typed messages from a user that initiated the callback request, to determine their intent for a callback. For example, their intent may be to have an hour-long meeting, which may factor into the decision by a callback cloud 420 to place a call shortly before one or both users may be required to start commuting to or from their workplace. Intent analysis may utilize any combination of text analytics, speech-to-text transcription, audio analysis, facial recognition, expression analysis, posture analysis, or other analysis techniques, and the particular technique or combination of techniques may vary according to such factors as the device type or interaction type (for example, speech-to-text may be used for a voice-only call, while face/expression/posture analysis may be appropriate fora video call), or according to preconfigured settings (that may be global, enterprise-specific, user-specific, device-specific, or any other defined scope).
Present in this embodiment is a brand interface server 530, which may expose the identity of, and any relevant API's or functionality for, any of a plurality of connected brands or on-premise callback components 510 which may be responsible for operating related brands, to elements in a callback cloud 520. In this wav elements of a callback cloud 520 may be able to connect to, and interact more directly with, systems and applications operating in a business' infrastructure such as a SIP server, which may be interfaced with a profile manager 521 to determine the exact nature of a user's profiles, sessions, and interactions in the system for added precision regarding their possible availability and most importantly, their identity. Also present in this embodiment is an intent analyzer 540, which analyzes spoken words or typed messages from a user that initiated the callback request, to determine their intent for a callback. For example, their intent may be to have an hour-long meeting, which may factor into the decision by a callback cloud 520 to place a call shortly before one or both users may be required to start commuting to or from their workplace. Intent analysis may utilize any combination of text analytics, speech-to-text transcription, audio analysis, facial recognition, expression analysis, posture analysis, or other analysis techniques, and the particular technique or combination of techniques may vary according to such factors as the device type or interaction type (for example, speech-to-text may be used for a voice-only call, while lace/expression/posture analysis may be appropriate for a video call), or according to preconfigured settings (that may be global, enterprise-specific, user-specific, device-specific, or any other defined scope).
Present in this embodiment is a brand interface server 630, which may expose the identity of, and any relevant API's or functionality for, any of a plurality of connected brands or on-premise callback components 610 which may be responsible for operating related brands, to elements in a callback cloud 620, through the use of an intent analyzer 640 and a broker server 650 to act as an intermediary between a callback cloud 620 and the plurality of other systems or services. In this way, elements of a callback cloud 620 may be able to connect to a broker server 650, and interact more indirectly with systems and applications operating in a business' infrastructure such as a SIP server, which may communicate with a profile manager 621 to determine the exact nature of a user's profiles, sessions, and interactions in the system kw added precision regarding their possible availability and most importantly, their identity. A broker server 650 operates as an intermediary between the services and systems of a callback cloud 620 and other external systems or services, such as an intent analyzer 640, PSTN 203, or the Internet 202. Also present in this embodiment is an intent analyzer 640, which analyzes spoken words or typed messages from a user that initiated the callback request, to determine their intent for a callback. For example, their intent may be to have an hour-long meeting, which may factor into the decision by a callback cloud 620 to place a call shortly before one or both users may be required to start commuting to or from their workplace. Intent analysis may utilize any combination of text analytics, speech-to-text transcription, audio analysis, facial recognition, expression analysis, posture analysis, or other analysis techniques, and the particular technique or combination of techniques may vary according to such factors as the device type or interaction type (for example, speech-to-text may be used for a voice-only call, while face/expression/posture analysis may be appropriate for a video call), or according to preconfigured settings (that may be global, enterprise-specific, user-specific, device-specific, or any other defined scope).
A caller attempts an initial communication request to a company via a client device 2001, which s routed to a preferred contact site 2010. The communication may be made using a VOIP (Voice over Internet Protocol) connection, TDM (Time Division multiplexing) or any other form of communication of which may not be limited to exclusively voice (such as SMS, text chat, video conferencing, etc.). In cases where the caller has previously interacted with a particular agent at the preferred contact site 2010, that agent's availability may be checked first, and the caller may be preferentially connected with that agent before the call is otherwise routed. If the particular agent is not available, the call may be routed to another agent. If no agents are available, the caller is asked whether he or she would like to be called back. If the caller agrees to a callback, the call is routed to a callback queue 2002 which may be a cloud-based system 2003. In some cases, the caller may be requested to indicate a preferred callback time. In some cases, the caller's history of communications may be stored in a database associated with the callback queue 2002, and may include information such as the caller's initial call times, attempted callback times, and the percentage of callbacks that were answered by the caller at the attempted callback times.
The caller's location in the callback queue 2002 is dynamically adjusted by a pacing algorithm 2200, which assigns a location in the queue according to the likelihood of success of a callback as determined by several factors, a non-limiting list of which includes the caller's preferred tinges for callbacks, the caller's history of communications, a preferred agent's availability, the availability of other agents, and external events which may affect callback success (e.g., holidays, sporting events, extreme weather, etc.). Prior to initiation of a callback according to the caller's location in the queue as determined by the pacing algorithm, agent availability may be checked including the availability of a preferred agent. The pacing algorithm may retrieve information pertaining to the customer or agent (or both) for determining an optimal time of attempting the callback fulfilment attempt. For example, a non-limiting list of information about callers that may be stored and retrieved includes the caller's phone number, preferred times fir callbacks, historical times of callbacks to the caller, historical percentages of answers by the caller at certain times, statistical data about individuals and groups similar to the caller, etc. In some embodiments, the pacing algorithm may also be used at the alternate contact site 2020 to determine callback times.
Each time a callback attempt is made, a callback counter may be updated. After a threshold number of unsuccessful callbacks is made 2006, the call may be routed to an alternate contact site 2020 in order to offload some of the call and/or callback volume from the preferred contact site 2010, thus leaving the preferred contact site 2010 with more resources to handle callbacks that are more likely to be successful. Information used to determine the threshold 2006 may include but is not limited to: the number of agents available at the site, the type of communication being used, the number of clients currently in the callback request queue, and the volume of callbacks at the alternate contact site 2020. In some embodiments, the threshold may also be used at the alternate contact site 2020 to determine wen to route the call for handling at additional alternate contact sites shown), which may in some embodiments be considered lower-tier contact sites, such that a hierarchy of alternate contact sites is established.
At the alternate contact site 2020, callbacks may be processed in a manner similar to that of the preferred contact site 2010, including use of a callback queue 2002, a pacing algorithm 2200, and in some embodiments a threshold 2006 for callback failures which causes the callback handling to be routed to additional alternate sites (not shown). In this embodiment, in order to attempt to maintain consistency of communications between the caller and a preferred agent, a secondary check for that particular agent's availability may be made immediately prior to making each callback attempt. At the alternate contact site 2020, a determination may be made to remove the caller from the queue 2007 after a pre-determined number of failed callback attempts, which pre-determined number may be the same as the threshold 2006 of failed callback attempt for the alternate contact site 2020.
In some embodiments, a machine learning algorithm may be trained to calculate probabilities of successful callbacks by using caller/callback training data similar to the various data types listed above. After training, actual caller data for each call or caller may be processed through the trained machine learning algorithm to calculate probabilities of successful callbacks allowing selection of those deemed most likely to result in a successful callback.
In some embodiments, an exemplary function for au optimal callback time made by the pacing algorithm may be a function such: f(n)=|(n*C)| where n is a base value for callback time, determined by the implementation, and C may be a number which is comprised of different rates and values obtained from agent stations and client data obtained from the cloud-based system, which is also dependent on the implementation, As an example, if customer hit rate (likelihood of an answer to a callback) has a weighted value of 0.2, number of agents available has a weighted value of 0.6 and the number of failed attempts as a weighted value of 0.3—an exemplary calculation of f(n) may be as follows: |(100*[0.2(0.5)−0.6(50)+0.4(2)])| where 100 corresponds to a base time value for callbacks and the value of C is dependent on the various weighted factors and corresponding amounts. With such a function, the increase in agents available would reduce the increased time between each callback, whereas the increase in failed attempts will add time to the time between callbacks. Although this function can provide a means for increasing/decreasing the callback time based on weighted values it is not the only function which may do so; the function used for calculating the callback time is determined by the implementation of the algorithm,
According to an aspect, the calculation used for determining a callback time may increase/decrease as the pacing algorithm obtains updated information. As an example, if the number of available agents increases between the callback attempts it is possible that the duration between callbacks will be reduced. According to another aspect of this exemplary function, the implementing programmer may wish to have maximum values associated with each relevant value in the calculation. As an example, the number of available agents may no longer decrease the dine between callbacks once it reaches a certain value (such as 100) in order to potentially maintain a certain minimum time for callbacks.
Hardware Architecture
