The disclosure relates to the field of contact center technology, specifically to the field of cloud-implemented automated callback systems.
Many businesses use groups of service representatives for communicating with clients who initiate communications with the business, such as by telephone calls. To most efficiently use the time and skills of each service representative, the service representatives may be organized into groups based on a skill set. For example, the groupings may be based on the representative's ability to handle client issues such as the opening of new accounts, billing issues and customer service issues on existing accounts.
Typically, if a client calls such a business, voice prompt menu choices enable the calling client to identify the issue for which the client requires service and the client is then queued for a service agent capable of handling the identified issue. As such, it is expected that clients who identify the purpose of their call as a “billing issue” will be queued for, and connected to, a service representative with the ability to handle billing issues. Similarly, it is expected that clients who identify the purpose of their call as a “customer service issue” will be queued for, and connected to, a service representative with the ability to handle customer service issues.
There are problems with existing communications systems, such as contact centers, including the following two problems. First, the voice prompt menus that are used to channel callers to the queue for the appropriate group of service agents are exacerbating to a client at best. It takes significant time to navigate the layered menus of voice prompts.
Second, waiting on-hold while a connection, be it a phone call, web chat, video conference, or other interaction type, is maintained in queue for connection to a service agent is also exacerbating to a client at best.
In an effort to reduce customer exacerbation caused by having to maintain a connection while on-hold in queue, secondary queue systems have been developed. A typical secondary queue system obtains a telephone number at which the calling client can be reached when a service representative is available (i.e., a call back number). The client disconnects, and then, at the proper time, a call back system establishes a connection to the client utilizing the call back number and couples the client to an available representative without waiting on-hold in queue. One exemplary system is disclosed in U.S. Pat. No. 6,563,921 to Williams et al. which is commonly assigned with the present application.
While such a system may make the experience of waiting for a connection to a service representative slightly less exasperating, it does not address the inconvenience of having to navigate an irritatingly slow and usually complicated voice prompt menu to enter the queue.
What is needed is a system and various methods for providing a callback cloud and related services that overcome the limitations of the prior art noted above.
Accordingly, the inventor has conceived and reduced to practice, in a preferred embodiment, a system and method for callback management, utilizing a callback cloud, a digital ledger, and smart callback contracts, brokering user to user communications and session establishment using an automated workflow built upon extensible root smart contract templates which can be configured to connect various users and brands. The system may comprise callback cloud, that may further comprise a callback manager, a brand interface server, an interaction manager, a media server, one or more blockchain digital ledgers, and various smart contracts which are used to autonomously respond to received user requests. The following non-limiting summary of the invention is provided for clarity, and should be construed consistently with embodiments described in the detailed description below.
A system has been devised for callback management utilizing smart callbacks, comprising: a brand interface server comprising at least a processor, a memory, and a first plurality of programming instructions stored in the memory and operating on the processor, wherein the first programming instructions, when operating on the processor, cause the processor to: communicate with a callback manager; send data related to smart callback contracts and agents to a callback manager; receive user calls to a brand; create a callback request upon a user requesting a call back from a brand; schedule a callback time with users based on user availability and agent scheduling; and forward the callback request and the scheduled callback time to a callback manager; and a callback manager comprising at least a processor, a memory, and a second plurality of programming instructions stored in the memory and operating on the processor, wherein the second programming instructions, when operating on the processor, cause the processor to: store and maintain global user profiles; store and maintain a blockchain ledger; communicate with a brand interface server; maintain relevant agent and brand data from the brand interface server; execute callback requests; determine environmental context and user intent; calculate estimated wait times for callbacks; receive a callback request and a scheduled callback time from the brand interface server; create a smart callback contract, the smart callback contract comprising default data fields, wherein the default data fields are populated with information from at least user profiles, agent and brand data, environmental context and user intent, and estimated wait times; execute the smart callback contract between consumers and agents at a specified time; connect the two parties, when the two first and second called parties are online; and validate the smart callback contract and add the callback to the blockchain ledger.
A method for callback management utilizing smart callbacks has been devised, comprising the steps of: communicating with a callback manager; sending data related to smart callback contracts and agents to a callback manager; receiving user calls to a brand; creating a callback request upon a user requesting a call back from a brand; scheduling a callback time with users based on user availability and agent scheduling; forwarding the callback request and the scheduled callback time to a callback manager; storing and maintaining global user profiles; storing and maintaining a blockchain ledger; communicating with a brand interface server; maintaining relevant agent and brand data from the brand interface server; executing callback requests; determining environmental context and user intent; calculating estimated wait times for callbacks; receiving a callback request and a scheduled callback time from the brand interface server; creating a smart callback contract, the smart callback contract comprising default data fields, wherein the default data fields are populated with information from at least user profiles, agent and brand data, environmental context and user intent, and estimated wait times; executing the smart callback contract between consumers and agents at a specified time; connecting the two parties, when the two first and second called parties are online; and validating the smart callback contract and adding the callback to the blockchain ledger.
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 by 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 callback management, utilizing a callback cloud, a digital ledger, and smart callback contracts, brokering user to user communications and session establishment using an automated workflow built upon extensible root smart contract templates which can be configured to connect various users and brands. The system may comprise callback cloud, that may further comprise a callback manager, a brand interface server, an interaction manager, a media server, one or more blockchain digital ledgers, and various smart contracts which are used to autonomously respond to received user requests.
One or more different aspects may be described in the present application. Further, for one or more of the aspects described herein, numerous alternative arrangements may be described; it should be appreciated that these are presented for illustrative purposes only and are not limiting of the aspects contained herein or the claims presented herein in any way. One or more of the arrangements may be widely applicable to numerous aspects, as may be readily apparent from the disclosure. In general, arrangements are described in sufficient detail to enable those skilled in the art to practice one or more of the aspects, and it should be appreciated that other arrangements may be utilized and that structural, logical, software, electrical and other changes may be made without departing from the scope of the particular aspects. Particular features of one or more of the aspects described herein may be described with reference to one or more particular aspects or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular aspects or figures with reference to which they are described. The present disclosure is neither a literal description of all arrangements of one or more of the aspects nor a listing of features of one or more of the aspects that must be present in all arrangements.
Headings of sections provided in this patent application and the title of this patent application are for convenience only, and are not to be taken as limiting the disclosure in any way.
Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical.
A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.
When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.
The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself.
Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.
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 as 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.
“Blockchain” as used herein refers to a growing list of records, called blocks, which are linked using cryptography. The blockchain is commonly a decentralized, distributed and public (or private) digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree root hash). For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without alteration of all subsequent blocks, which requires consensus of the network majority. In verifying or validating a block in the blockchain, a hashcash (or other algorithm) algorithm generally requires the following parameters: a service string, a nonce, and a counter. The service string can be encoded in the block header data structure, and include a version field, the hash of the previous block, the root hash of the Merkle tree of all transactions (or information or data) in the block, the current time, and the difficulty level. The nonce can be stored in an extraNonce field, which is stored as the left most leaf node in the Merkle tree. The counter parameter is often small at 32-bits so each time it wraps the extraNonce field must be incremented (or otherwise changed) to avoid repeating work. When validating or verifying a block, the hashcash algorithm repeatedly hashes the block header while incrementing the counter & extraNonce fields. Incrementing the extraNonce field entails recomputing the Merkle tree, as the transaction or other information is the left most leaf node. The body of the block contains the transactions or other information. These are hashed only indirectly through the Merkle root.
“Smart contracts” as used herein are simply programs stored on a blockchain that run when predetermined conditions are met. They typically are used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary's involvement or time loss. They can also automate a workflow, triggering the next action when conditions are met.
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.
Furthermore, callback cloud 201 may integrate with or be communicatively coupled with various components and/or services including, but not limited to, profile manager 250, environment analyzer 260, callback manager 270, interaction manager 280, and media server 290. These components are described below with reference to
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 improves customer satisfaction by saving additional time with 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 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, emails, 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 identity 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 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 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 way, 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 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).
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, services, or network endpoints 660, 670. 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 for 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).
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 other than a cellular phone 212, they may be forwarded by brand interface server 2027 to brands 2010 operated by a business in the manner described herein. For example, a cellular phone call may be placed over PSTN 203 and received by brand interface server 2027 before being handled by a call router 2014 and generating a session with a SIP server 2012, the SIP server creating a session with a callback cloud 2020 with a profile manager 2021 if the call cannot be completed, resulting in a callback being required. A brand interface server 2027 in a callback cloud 2020 receives initial requests to connect to callback cloud 2020 and instructs profile manager 2021 to forward relevant user profile information to a callback manager 2023, which may further request environmental context data from an environment analyzer 2022. 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 2022.
A callback manager 2023 centrally manages all callback data, creating a smart callback contract 2029 which may be used to execute a workflow and manage the data for a particular callback, and communicates with an interaction manager 2024 which handles requests to make calls and bridge calls, which go out to a media server 2025 which actually makes the calls as requested. In this way, the media server 2025 may be altered in the manner in which it makes and bridges calls when directed, but the callback manager 2023 does not need to adjust itself, due to going through an intermediary component, the interaction manager 2024, as an interface between the two. A media server 2025, 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.
Present in this embodiment is a brand interface server 2027, which may expose the identity of, and any relevant API's or functionality for, any of a plurality of connected brands 2010, to elements in a callback cloud 2020. In this way, elements of a callback cloud 2020 may be able to connect to, and interact more directly with, systems and applications operating in a business' infrastructure such as a SIP server 2012, which may be interfaced with a profile manager 2021 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 2026, 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 2020 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).
According to an embodiment, callback manager 2023 may utilize and orchestrate blockchain 2028 technology to improve end user experience, satisfaction, and security when interacting with an enterprise 220 such as a contact center. According to some embodiments, the blockchain 2028 may be implemented as a private blockchain. Operating a private blockchain, callback cloud 2020 is able to read and write data contained within the private blockchain in order to create and manage smart callback contracts 2029. Smart callback contracts 2029 may be implemented using smart contract technology. Smart contracts work by following simple “if/when . . . then . . . ” statements that are written into code on a blockchain. A network of computers (e.g., callback cloud 2020) executes the actions when predetermined conditions have been met and verified. These actions could include, but are not limited to, releasing funds to the appropriate parties, applying a change of service, updating a user profile, executing a scheduled callback between the appropriate parties, sending notifications, and routing requests. The blockchain is then updated when the transaction is completed. That means the transaction cannot be changed, and only parties who have been granted permission can see the results.
Callback cloud 2020 may utilize a root smart callback contract 2029 template that can be configured to execute a callback using information specific to a given callback request. The root template may be comprised of a plurality of default fields which may be populated with user or enterprise-specific information during smart callback contract creation. For example, in one embodiment, default fields may include, but are not limited to, participating parties' identities (e.g., callback requestor and a callback recipient), participants contact information (e.g., phone number, extension number, email address, social media handle, etc.), communication device(s), method of communication (e.g., phone call, email, SMS message, VoIP call, etc.), scheduled callback time, brand information (e.g., from brand interface server 2027), context data (e.g., environmental and intent context, historical user profile data, past interactions, links to previous smart callback contracts, etc.). By utilizing a root template, callback cloud 2020 can efficiently and dynamically create extensible smart callback contracts 2029 for both simple and complex callback use cases.
According to an embodiment, the root contract template may comprise pre-coded logic and/or computer readable instructions which may perform a variety of actions, such as executing a callback via a smart callback contract 2029. The pre-coded logic and/or computer readable instructions may be completed when one or more default data fields are populated with information. What this means is that the behavior of the smart contract 2029 created using the root template is at least partially determined based off the values input into the default fields. For example, a root smart callback contract 2029 template has pre-coded logic to execute when a certain trigger occurs, the trigger being a specified time, and wherein the time value to be used within the pre-coded trigger event logic is the scheduled callback time that was input into the corresponding default field during smart callback contract 2029 construction. As another example, the root smart callback contract 2029 template has pre-coded logic to connect two parties via method of communication, wherein the method of communication default field value determines the underlying logic used to connect two parties, such as method of communication being email which would have different connecting logic than a method of communication being a phone call. In this way, system 2000 can use a root contract template from which to create a broad range of smart contracts in order to negotiate session establishment between and among a plurality of individual users, enterprises and their systems, and brands.
According to an embodiment, the callback cloud 2020 can be or may include any servers that can be used to keep a digital ledger. A digital ledger is where multiple copies of the same blockchain(s) 2028 are stored on separate servers in order to validate a transaction (e.g., execution of a callback). The digital ledger typically has copies of a single blockchain 2028 that is used for all transactions (for multiple users of the contact center) in a contact center or other enterprise 220. When a new transaction occurs in the callback cloud 2020, if the transaction is validated, a new block is added to the blockchains 2028 on each of the servers to keep a record of the transaction. In one embodiment there may be a separate blockchain 2028 associated with each user and stored as part of a user profile.
Callback manager 2023 may receive, retrieve, or otherwise obtain and work with a user's profile as managed by a profile manager 2021, with environmental context from an environment analyzer 2022, with intent as determined from intent analyzer 2026 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 2024 to physically place and bridge the calls with a media server 2025. When a callback is requested by a system user, callback manager 2023 may populate the fields of a smart callback contract 2029 with the obtained user profile information, the environmental and intent context, and a scheduled callback time based on EWT information (if provided). Smart callback contracts 2029 may be triggered to connect a callback requestor with a callback recipient when the scheduled callback time occurs. When the scheduled callback time occurs the code (i.e., machine readable instructions) within the smart callback contract 2029 may cause interaction manager 2024 to bridge the callback request and then connect the two parties using media server 2025. After the parties have been connected, the smart callback contract may then be validated and added to the blockchain 2028 digital ledger by callback manager 2023. In this way, a user may communicate via the callback cloud 2020 with another user on a PBX system 2011, or with automated services hosted on a chat server 2015, and if they do not successfully place their call or need to be called back by a system, a callback cloud 2020 may find an optimal time to bridge a call between the callback requestor and callback recipient, as necessary.
