     BACKGROUND OF THE INVENTION 
     Field of the Art 
     The disclosure relates to the field of contact center technology, specifically to the field of cloud-implemented automated callback systems. 
     Discussion of the State of the Art 
     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&#39;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.

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. 
     Conceptual Architecture 
       FIG.  1    (PRIOR ART) is a block diagram illustrating an on-premise callback system. A possible plurality of consumer endpoints  110  may be connected to either a Public Switch Telephone Network (“PSTN”)  103  or the Internet  102 , further connecting them to an on-premise callback system  120 . Such consumer endpoints may include a telephone  111  which connects over a PSTN, a mobile phone  112  capable of connecting over either a PSTN  103  or the Internet  102 , a tablet  113  capable of connecting over either a PSTN  103  or the Internet  102 , or a laptop  114  or Personal Computer (“PC”)  115  capable of connecting over the Internet  102 . Connected to the Internet  102  is a callback organizer  140 , which organizes callback data across internet  102  and PSTN  103  connections to consumer endpoints  110  and a local area network or wide area network  130  to further on-premise components. Other on-premise or inter-organizational endpoints may include agent cellular devices  121 , an internal telephone switch  122  and telephone  127  which connect to the PSTN  103 , a PC  126  or a tablet  128  that may be connected over a LAN or WAN  130 . These brand endpoints in an on-premise callback system  120  may be involved in callbacks over the PSTN  103  or internet  102  connections, as organized by a callback organizer  140 , which is responsible for all aspects of organizing callback requests including managing and calculating Estimated Wait-Times (EWT), managing agent schedule data, managing consumer queues and the agents logged into those queues, and other typical functions of an on-premise callback system. 
       FIG.  2    is a block diagram of a preferred embodiment of the invention, illustrating an exemplary architecture of a system  200  for providing a callback cloud service. According to the embodiment, callback cloud  201  may receive requests  240  via a plurality of communications networks such as a public switched telephone network (PSTN)  203  or the Internet  202 . These requests may comprise a variety of communication and interaction types, 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 via PSTN  203 . Such communications networks may be connected to a plurality of consumer endpoints  210  and enterprise endpoints  220  as illustrated, according to the particular architecture of communication network involved. Exemplary consumer endpoints  210  may include, but are not limited to, traditional telephones  211 , cellular telephones  212 , mobile tablet computing devices  213 , laptop computers  214 , or desktop personal computers (PC)  215 . Such devices may be connected to respective communications networks via a variety of means, which may include telephone dialers, VOIP telecommunications services, web browser applications, SMS text messaging services, or other telephony or data communications services. It will be appreciated by one having ordinary skill in the art that such means of communication are exemplary, and many alternative means are possible and becoming possible in the art, any of which may be utilized as an element of system  200  according to the invention. 
     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 further 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 may 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, due 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&#39;s profile as managed by a profile manager  250 , with environmental context from 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&#39;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&#39;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. 
       FIG.  3    is a block diagram illustrating an exemplary system architecture for a callback cloud operating over a public switched telephone network and the Internet, and connecting to a variety of other brand devices and services, according to an embodiment. A collection of user brands  310  may be present either singly or in some combination, possibly including a Public Branch Exchange (“PBX”)  311 , a Session Initiation Protocol (“SIP”) server  312 , a Customer Relationship Management (“CRM”) server  313 , a call router  314 , or a chat server  315 , or some combination of these brands. These brands  310  may communicate over a combination of, or only one of, a Public Switched Telephone Network (“PSTN”)  203 , and the Internet  202 , to communicate with other devices including a callback cloud  320 , a company phone  221 , or a personal cellular phone  212 . A SIP server  312  is responsible for initiating, maintaining, and terminating sessions of voice, video, and text or other messaging protocols, services, and applications, including handling of PBX  311  phone sessions, CRM server  313  user sessions, and calls forwarded via a call router  314 , all of which may be used by a business to facilitate diverse communications requests from a user or users, reachable by phone  221 ,  212  over either PSTN  203  or the Internet  202 . A chat server  315  may be responsible for maintaining one or both of text messaging with a user, and automated voice systems involving technologies such as an Automated Call Distributor (“ACD”), forwarding relevant data to a call router  314  and CRM server  313  for further processing, and a SIP server  312  for generating communications sessions not run over the PSTN  203 . Various systems may also be used to monitor their respective interactions (for example, chat session by a chat server  315  or phone calls by an ACD or SIP server  312 ), to track agent and resource availability for producing EWT estimations. 
     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, 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&#39;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&#39;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. 
       FIG.  4    is a block diagram illustrating an exemplary system architecture for a callback cloud including a brand interface server and intent analyzer, operating over a public switched telephone network and the Internet, and connected to a variety of other brand devices and services, according to an embodiment. According to this embodiment, many user brands  410  are present, including PBX system  411 , a SIP server  412 , a CRM server  413 , a call router  414 , and a chat server  415 , which may be connected variously to each other as shown, and connected to a PSTN  203  and the Internet  202 , which further connect to a cellular phone  212  and a landline  221  or other phone that may not have internet access. Further shown is a callback cloud  420  contains multiple components, including a profile manager  421 , environment analyzer  422 , callback manager  423 , interaction manager  424 , and media server  425 , which function as described in previous embodiments and, similarly to user brands  410  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  203  or the internet  202 . 
     Present in this embodiment is a brand interface server  430 , which may expose the identity of, and any relevant API&#39;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&#39; infrastructure such as a SIP server  412 , which may be interfaced with a profile manager  421  to determine the exact nature of a user&#39;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). 
       FIG.  5    is a block diagram illustrating an exemplary system architecture for a hybrid callback system operating with a callback cloud and an on-premise callback stack, according to an embodiment. According to this embodiment, an on-premise callback stack  510  is shown, which contains multiple components, including a profile manager  511 , environment analyzer  512 , callback manager  513 , interaction manager  514 , and media server  515 , which are interconnected in various ways as depicted in the diagram, and connected to a call aggregator  550  which aggregates user calls into queues using data received from an on-premise callback stack  510 , and allowing these aggregated and queued calls to then be managed by a callback manager  513 . A call aggregator may be connected to either of a PSTN  203  or the internet  202 , or it may be connected to both and receive call data from both networks as needed. Further shown is a callback cloud  520  which contains multiple similar components, including a profile manager  521 , environment analyzer  522 , callback manager  523 , interaction manager  524 , and media server  525 , which function as described in previous embodiments and, similarly to an on-premise callback stack  510  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  203  or the internet  202 . 
     Present in this embodiment is a brand interface server  530 , which may expose the identity of, and any relevant API&#39;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&#39; infrastructure such as a SIP server, which may be interfaced with a profile manager  521  to determine the exact nature of a user&#39;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). 
       FIG.  6    is a block diagram illustrating an exemplary system architecture for a hybrid callback system operating with a callback cloud and an on-premise callback stack, and a broker server, according to an embodiment. According to this embodiment, an on-premise callback stack  610  is shown, which connects to a call aggregator  650  which aggregates user calls into queues using data received from an on-premise callback stack  610 , and allowing these aggregated and queued calls to then be managed by a callback manager  613 . The features and connections of the on-premise callback stack  610  are similar to that shown in  FIG.  5 ,  510   . A call aggregator may be connected to either of a PSTN  203  or the internet  202 , or it may be connected to both and receive call data from both networks as needed. Further shown is a callback cloud  620  which contains multiple components, including a profile manager  621 , environment analyzer  622 , callback manager  623 , interaction manager  624 , and media server  625 , which function as described in previous embodiments and, similarly to an on-premise callback stack  610  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  203  or the internet  202 . 
     Present in this embodiment is a brand interface server  630 , which may expose the identity of, and any relevant API&#39;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&#39; infrastructure such as a SIP server, which may communicate with a profile manager  621  to determine the exact nature of a user&#39;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). 
       FIG.  7    (PRIOR ART) is a method diagram illustrating steps in the operation of an on-premise callback system. A consumer may initiate a callback request to a brand handled or managed at a premise  710 , such as if a consumer were to place a phone call to customer service for a corporation and the contact center or centers were unable to immediately answer their call. An estimated wait time (EWT) is calculated for consumers in the queue based on the condition of the contact center  720 , determining a possible callback time based on the EWT and a consumer-accepted time  730 , such as calling a consumer back in 10 minutes when an agent at the premise is available and their spot in the queue is reached  740 . Regardless of the specific time chosen, a first callback is attempted  740  when the selected time is reached, calling a first party of either the brand agent or the consumer, followed by calling of the second party if and when the first party comes online  750 . When both parties are online they are connected together such as bridging the two phones to a single call  760 , and any callback object used to manage the callback data is deleted after the successful callback. 
       FIG.  8    is a method diagram illustrating the use of a callback cloud for intent-based active callback management, according to an embodiment. According to an embodiment, a callback cloud  320  must receive a request for a callback to a callback recipient, from a callback requester  810 . This refers to an individual calling a user of a cloud callback system  320 , being unable to connect for any reason, and the system allowing the caller to request a callback, thus becoming the callback requester, from the callback recipient, the person they were initially unable to reach. A callback object is instantiated  820 , using a callback manager  323 , which is an object with data fields representing the various parts of callback data for a callback requester and callback recipient, and any related information such as what scheduled times may be possible for such a callback to take place. Global profiles may then be retrieved  830  using a profile manager  321  in a cloud callback system, as well as an analysis of environmental context data  840 , allowing for the system to determine times when a callback may be possible for a callback requestor and callback recipient both  850 . When such a time arrives, a first callback is attempted  860  to the callback requestor or callback recipient, and if this succeeds, a second call is attempted to the second of the callback requestor and callback recipient  870 , allowing a media server  325  to bridge the connection when both are online, before deleting the callback object  880 . 
       FIG.  9    is a method diagram illustrating the operation of a distributed hybrid callback system architecture utilizing cloud services and on-premise services, according to an embodiment. First, a consumer places a call to a brand  905 , resulting in on-premise datastores and services being queried by a callback cloud if such a callback cloud is properly configured and online  910 . A callback cloud may be utilized normally to manage consumer queues, calculate EWT&#39;s, manage agent statuses and their call lengths and queue membership, and other common callback system functions, with the querying of on-premise datastores and services  915 . If a callback cloud is unavailable however, an on-premise callback system may be utilized as described in prior art figures, without use of cloud services  920 . If a cloud callback system is available and configured, but on-premise callback services are unavailable, a cloud callback system can utilize last-known data such as last-known EWT&#39;s and manage consumer callbacks as normal without being able to query new data from on-premise datastores  925 , potentially resulting in slightly less consistent or optimal callback handling initially, but still maintaining the system. 
       FIG.  10    is a method diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a premise callback server failure. Agent data such as schedules and their profiles regarding average call duration are stored on-premise and co-maintained in a cloud callback system  1005 . Also co-maintained between a callback cloud and on-premise callback system are callback objects, which hold data regarding a particular callback request including the requester, the time to attempt the callback, and any information regarding the brand or specific agent to perform the callback, if applicable  1010 . Should an on-premise callback server fail  1015 , a callback cloud may take over management and execution of callback objects until said on-premise callback server recovers  1020 , essentially behaving as the new callback system for the contact center. Should a contact center&#39;s callback server come back online, data is re-distributed to it from the callback cloud system  1025 , with the on-premise server regaining management and execution of callback objects from the callback cloud  1030 . 
       FIG.  11    is a method diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a total system failure. Agent data such as schedules and their profiles regarding average call duration are stored on-premise and co-maintained in a cloud callback system  1105 . Also co-maintained between a callback cloud and on-premise callback system are callback objects, which hold data regarding a particular callback request including the requester, the time to attempt the callback, and any information regarding the brand or specific agent to perform the callback, if applicable  1110 . Should an entire on-premise callback stack fail  1115 , a callback cloud may take over management and execution of all callback-related activities including callback execution, EWT calculation  1125 , and more  1120 , until said on-premise callback stack recovers  1130 , essentially behaving as the new callback system for the contact center. Should a contact center&#39;s callback stack come back online, data is re-distributed to it from the callback cloud system  1130 , with the on-premise server regaining management of callback systems and updating their data from the callback cloud&#39;s data as appropriate  1135 . 
       FIG.  12    is a method diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a premise automatic call distribution and callback server failure. Agent data such as schedules and their profiles regarding average call duration are stored on-premise and co-maintained in a cloud callback system  1205 . Also co-maintained between a callback cloud and on-premise callback system are callback objects, which hold data regarding a particular callback request including the requester, the time to attempt the callback, and any information regarding the brand or specific agent to perform the callback, if applicable  1210 . Should an on-premise Automatic Call Distribution (ACD) system and callback server fail  1215 , a callback cloud may take over management and execution of call distribution and callback-related activities as necessary  1220 , with on-site agents interfacing with cloud services for example through a web-browser  1225  and with remaining on-site resources being made available to the cloud infrastructure as needed such as for the purposes of recalculating consumer EWT&#39;s  1230 , until the on-premise callback stack recovers, essentially behaving as the new callback system for the contact center. Should a contact center&#39;s callback stack come back online, data is re-distributed to it from the callback cloud system  1235 , with the on-premise server regaining management of callback systems and updating their data from the callback cloud&#39;s data as appropriate  1240 . 
       FIG.  13    is a method diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a partial system failure, using a broker server to leverage third-party resources for failure recovery. Agent data such as schedules and their profiles regarding average call duration are stored on-premise and co-maintained in a cloud callback system  1305 . Also co-maintained between a callback cloud and on-premise callback system are callback objects, which hold data regarding a particular callback request including the requester, the time to attempt the callback, and any information regarding the brand or specific agent to perform the callback, if applicable  1310 . Should an on-premise Automatic Call Distribution (ACD) system and callback server fail  1315 , a callback cloud may take over management and execution of call distribution and callback-related activities as necessary  1320 , with a broker server interfacing with third-party services such as other contact centers to leverage other resources to manage the load during the premise downtime  1325 . Consumer EWT is recalculated if needed  1330 , and should a contact center&#39;s callback stack come back online, data is re-distributed to it from the callback cloud system  1335 , with the on-premise server regaining management of callback systems and updating their data from the callback cloud&#39;s data as appropriate  1340 . 
       FIG.  14    is a method diagram illustrating calculation and recalculation of an estimated wait-time (EWT) for a distributed callback system. An agent may log into a queue or be assigned automatically to a queue by a callback manager or call aggregator  1405 , allowing consumers to call or open communications with a brand&#39;s agents  1410 . An average call length for each queue is calculated  1415  utilizing branching averages, for example most calls may be calculated to take 4 minutes, but a call that has already progressed to 3 minutes may be calculated to have a 70% chance of reaching at least 5 minutes in length. Upon more consumers than agents becoming available, or any change in the amount of available agents or consumers in the queue, calculate the time based on these averages that the next available agent will be free to engage in a call with the consumer  1420 . This is utilized as the Estimated Wait Time (EWT) for a consumer  1425 , and a consumer may be informed of the EWT for callback purposes  1430 . 
       FIG.  15    is a message flow diagram illustrating the operation of a distributed hybrid callback system architecture utilizing cloud services and on-premise services, according to an embodiment. A consumer  1505 , callback cloud  1510 , and on-premise callback system  1515  are the principle actors in data transmissions, with specific components of a callback cloud  1510  or on-premise callback system  1515  handling data internally to the respective systems, and a consumer  1505  potentially using one of many common endpoints such as a cellphone, landline phone, PC, tablet, or laptop. A consumer  1505  may place a call from one such endpoint, to a contact center  1520 , which may be received by a callback cloud  1510  that is online and managing callback data for a given premise callback system  1515 . An on-premise callback system  1515  may co-maintain data including average call times for certain queues, agent availability, agent schedules, and more, with a callback cloud  1525 , allowing a callback cloud to execute a callback  1530  to a consumer  1505 , connecting agents and consumers with said callbacks as necessary. If a callback cloud is unavailable, an on-premise callback system instead executes the callback  1535 , the callback object being used to attempt to open communications with the consumer  1505  and an on-premise agent. 
       FIG.  16    is a message flow diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a premise callback server failure. A consumer  1605 , callback cloud  1610 , and on-premise callback system  1615  are the principle actors in data transmissions, with specific components of a callback cloud  1610  or on-premise callback system  1615  handling data internally to the respective systems, and a consumer  1605  potentially using one of many common endpoints such as a cellphone, landline phone, PC, tablet, or laptop. An on-premise callback system  1615  may continuously co-maintain data including average call times for certain queues, agent availability, agent schedules, and more, with a callback cloud  1620 , before a premise callback server may go offline and be unable to execute callbacks to consumers. In such an event, an on-premise failure message  1625  is sent to a callback cloud  1610 , informing a callback cloud to execute any consumer callback requests  1630  to a consumer  1605 , connecting agents and consumers with said callbacks as necessary. In such an event, the callback cloud may execute customer callbacks using the previously co-maintained data  1635 , the callback object being used to attempt to open communications with the consumer  1605  and an on-premise agent. In the event of an on-premise callback server coming back online, current data regarding the brand and on-premise callback data is forwarded back to a premise callback system  1635 , for example to update the server with data on completed and yet-to-complete callback requests. 
       FIG.  17    is a message flow diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a total system failure. A consumer  1705 , callback cloud  1710 , and on-premise callback system  1715  are the principle actors in data transmissions, with specific components of a callback cloud  1710  or on-premise callback system  1715  handling data internally to the respective systems, and a consumer  1705  potentially using one of many common endpoints such as a cellphone, landline phone, PC, tablet, or laptop. An on-premise callback system  1715  may continuously co-maintain data including average call times for certain queues, agent availability, agent schedules, and more, with a callback cloud  1720 , before total on-premise callback system failure, such as by a power outage affecting their callback system equipment and services. In such an event, an on-premise failure message  1725  is sent to a callback cloud  1710 , informing a callback cloud to first re-calculate and send customer Estimated Wait Times (“EWT”) for customers  1730 , since call distribution has been interrupted and must now be accomplished by the cloud service. In such an event, the callback cloud may execute customer callbacks using the previously co-maintained data  1735 , the callback object being used to attempt to open communications with the consumer  1705  and an on-premise agent. In the event of an on-premise callback server coming back online, current data regarding the brand and on-premise callback data is forwarded back to a premise callback system  1740 , for example to update the server with data on completed and yet-to-complete callback requests. 
       FIG.  18    is a message flow diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a premise automatic call distribution and callback server failure. A consumer  1805 , callback cloud  1810 , and on-premise callback system  1815  are the principle actors in data transmissions, with specific components of a callback cloud  1810  or on-premise callback system  1815  handling data internally to the respective systems, and a consumer  1805  potentially using one of many common endpoints such as a cellphone, landline phone, PC, tablet, or laptop. An on-premise callback system  1815  may continuously co-maintain data including average call times for certain queues, agent availability, agent schedules, and more, with a callback cloud  1820 , before on-premise Automatic Call Distribution (“ACD”) and callback servers may go offline and be unable to execute callbacks to consumers or adequately manage incoming calls. In such an event, an on-premise failure message  1825  is sent to a callback cloud  1810 , informing a callback cloud to first re-calculate and send customer Estimated Wait Times (“EWT”) for customers  1835 , since call distribution has been interrupted and must now be accomplished by the cloud service. In the meantime, agents and services continue to interface with the cloud  1830 . In such an event, the callback cloud may execute customer callbacks using the previously co-maintained data  1840 , the callback object being used to attempt to open communications with the consumer  1805  and an on-premise agent. In the event of an on-premise callback server coming back online, current data regarding the brand and on-premise callback data is forwarded back to a premise callback system  1845 , for example to update the server with data on completed and yet-to-complete callback requests. 
       FIG.  19    is a message flow diagram illustrating the use of callback cloud services to aid in the recovery of an on-premise callback system in the event of a partial system failure, using a broker server to leverage third-party resources for failure recovery. A consumer  1905 , callback cloud  1910 , and on-premise callback system  1915  are the principle actors in data transmissions, with specific components of a callback cloud  1910  or on-premise callback system  1915  handling data internally to the respective systems, and a consumer  1905  potentially using one of many common endpoints such as a cellphone, landline phone, PC, tablet, or laptop. An on-premise callback system  1915  may continuously co-maintain data including average call times for certain queues, agent availability, agent schedules, and more, with a callback cloud  1920 , before on-premise Automatic Call Distribution (“ACD”) and callback servers may go offline and be unable to execute callbacks to consumers or adequately manage incoming calls  1930 . In such an event, an on-premise failure message  1925  is sent to a callback cloud  1910 , informing a callback cloud to first re-calculate and send customer Estimated Wait Times (“EWT”) for customers  1940 , since call distribution has been interrupted and must now be accomplished by the cloud service. In such an event, the callback cloud may execute customer callbacks using the previously co-maintained data  1945 , the callback object being used to attempt to open communications with the consumer  1905  and an on-premise agent. In the event of an on-premise callback server coming back online, current data regarding the brand and on-premise callback data is forwarded back to a premise callback system  1950 , for example to update the server with data on completed and yet-to-complete callback requests. 
       FIG.  24    is a block diagram illustrating an exemplary system architecture for a hybrid callback system operating with a callback cloud  2400  and an on-premise callback stack, and a biometric authenticator  2401 , according to an embodiment. According to this embodiment, components of a callback cloud  2400  may mirror the components  921 - 925  in previous figures (at least  FIG.  3    through  FIG.  6   ). According to this embodiment, an on-premise callback stack  610  is shown, which connects to a call aggregator  650  which aggregates user calls into queues using data received from an on-premise callback stack  610 , and allowing these aggregated and queued calls to then be managed by a callback manager  613 . The features and connections of the on-premise callback stack  610  are similar to that shown in  FIG.  5 ,  510   . A call aggregator may be connected to either of a PSTN  203  or the internet  202 , or it may be connected to both and receive call data from both networks as needed. Further shown is a callback cloud  620  which contains multiple components, including a biometric authenticator  2401 , a profile manager  621 , environment analyzer  622 , callback manager  623 , interaction manager  624 , and media server  625 , which function as described in previous embodiments and, similarly to an on-premise callback stack  610  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  203  or the internet  202 . 
     Present in this embodiment is a biometric authenticator  2401 . A biometric authenticator  2401  replaces or supplements typical authentication practices such as verbal challenges or pin numbers by providing a more secure means of authentication. In some implementations, a biometric authenticator  2401  requests authentication from a user from a biometric sensor on a mobile device  2402 / 2403 . For example, during the requesting of a callback from a user, a callback cloud service  2400  generates a request for biometric authentication which is sent to the user device  2402 / 2403  that then collects and verifies the biometrics and identity of the user. The verification, whether successful or not, is sent back to the cloud service  2400  which then continues with the callback request procedures set forth in the various embodiments herein with the added function of the user having already been verified or not by the callback cloud  2400 . In the scenario in which a user is successfully verified, the callback object may comprise the verification information so that when the user is called back, the user may or may not need to be verified a second time. 
     A biometric authenticator  2401  may generate a biometric request in one or more various ways. The first of which is to use Dual Tone Multi Frequency (DTMF) signals during the request for a callback. This may be implemented when a user is currently interacting with an IVR system to request a callback, the callback cloud  2400  generates a text message to the user&#39;s device  2402 / 2403  that comprises a URL scheme to the device&#39;s biometric authentication application, so that when the user clicks the URL, the biometric authentication application is opened on the device. From here there are two anticipated methods to notify the callback cloud  2400  of a successful or failed authentication attempt. Upon completion of the authentication attempt, a series of numbers may be shown to the user, the series of numbers indicating success or failure, so that the user may enter those numbers in the dial pad thus transmitting an encrypted message to the callback cloud  2400 . The callback cloud deciphers the series of dial tones to determine whether the attempt was successful or not based on the series of numbers, i.e., DTMF tones, received. Another method encompasses an application present on the device that automatically enters the dial tones for the user. These methods are useful when interacting via a PSTN network  203 . A second anticipated method of requesting, transmitting, and confirming biometric authentication between a user device  2402 / 2403  and the callback cloud  2400  is to use an application on the user&#39;s device that may be triggered to open a biometrics request from a user and automatically transmit the biometric information to the callback cloud  2400 . This method is best used when Internet  202  is available. A third anticipated method is to use a third party biometric service with an API for determining the identity of the user. Other alternative methods comprise voice matching, facial recognition, and the like. 
     Irrespective of the method, the user&#39;s identity information from the biometric authentication process maybe compared to records stored on either or both the callback cloud  2400  or the on premise callback stack  610 . 
       FIG.  25    is a method diagram illustrating the use of a callback cloud using biometric authentication, according to an embodiment. In a first step  2500 , a user calls a brand or entity desiring to speak with an agent, but is placed in a queue and given the option to receive a callback. In a second step, the user opts for a callback  2501  which triggers the generation of a biometric authentication request  2502 . The generated request may be in the form of a text message, API call, push notification, and the like. The user&#39;s device receives the generated biometric authentication request sent from a callback cloud service  2503  that prompts the user to fulfill the biometric request. The biometric information from the user&#39;s device is received by the callback cloud  2504  and is stored in a callback object. Along with the identity of the user, an identity indicator may also be stored in the callback object  2506  either verifying or denying the user as an authorized user  2505 . Verification may take place by comparing the biometric information with stored user information in a user profile stored in either or both a callback cloud service and a callback stack. Verification may also take place on the user&#39;s device by connecting with a locally stored database synchronized with the data stored in either or both a callback cloud service and a callback stack. Verification may also take place using an API and a third party verification service. The identity and identity indicator may be used to automatically grant or deny permissions to the user to gain access to private information from an automated system  2507 . The identity and identity indicator may be provided to an agent to allow the agent to determine the level of access of the user  2507 . The identity and identity indicator may be used to determine if the user must reauthenticate during the callback, either before or during being connected with an agent. The identity and identity indicator may be stored for future analysis or provenance measures. 
     Hardware Architecture 
     Generally, the techniques disclosed herein may be implemented on hardware or a combination of software and hardware. For example, they may be implemented in an operating system kernel, in a separate user process, in a library package bound into network applications, on a specially constructed machine, on an application-specific integrated circuit (ASIC), or on a network interface card. 
     Software/hardware hybrid implementations of at least some of the aspects disclosed herein may be implemented on a programmable network-resident machine (which should be understood to include intermittently connected network-aware machines) selectively activated or reconfigured by a computer program stored in memory. Such network devices may have multiple network interfaces that may be configured or designed to utilize different types of network communication protocols. A general architecture for some of these machines may be described herein in order to illustrate one or more exemplary means by which a given unit of functionality may be implemented. According to specific aspects, at least some of the features or functionalities of the various aspects disclosed herein may be implemented on one or more general-purpose computers associated with one or more networks, such as for example an end-user computer system, a client computer, a network server or other server system, a mobile computing device (e.g., tablet computing device, mobile phone, smartphone, laptop, or other appropriate computing device), a consumer electronic device, a music player, or any other suitable electronic device, router, switch, or other suitable device, or any combination thereof. In at least some aspects, at least some of the features or functionalities of the various aspects disclosed herein may be implemented in one or more virtualized computing environments (e.g., network computing clouds, virtual machines hosted on one or more physical computing machines, or other appropriate virtual environments). 
     Referring now to  FIG.  20   , there is shown a block diagram depicting an exemplary computing device  10  suitable for implementing at least a portion of the features or functionalities disclosed herein. Computing device  10  may be, for example, any one of the computing machines listed in the previous paragraph, or indeed any other electronic device capable of executing software- or hardware-based instructions according to one or more programs stored in memory. Computing device  10  may be configured to communicate with a plurality of other computing devices, such as clients or servers, over communications networks such as a wide area network a metropolitan area network, a local area network, a wireless network, the Internet, or any other network, using known protocols for such communication, whether wireless or wired. 
     In one aspect, computing device  10  includes one or more central processing units (CPU)  12 , one or more interfaces  15 , and one or more busses  14  (such as a peripheral component interconnect (PCI) bus). When acting under the control of appropriate software or firmware, CPU  12  may be responsible for implementing specific functions associated with the functions of a specifically configured computing device or machine. For example, in at least one aspect, a computing device  10  may be configured or designed to function as a server system utilizing CPU  12 , local memory  11  and/or remote memory  16 , and interface(s)  15 . In at least one aspect, CPU  12  may be caused to perform one or more of the different types of functions and/or operations under the control of software modules or components, which for example, may include an operating system and any appropriate applications software, drivers, and the like. 
     CPU  12  may include one or more processors  13  such as, for example, a processor from one of the Intel, ARM, Qualcomm, and AMD families of microprocessors. In some aspects, processors  13  may include specially designed hardware such as application-specific integrated circuits (ASICs), electrically erasable programmable read-only memories (EEPROMs), field-programmable gate arrays (FPGAs), and so forth, for controlling operations of computing device  10 . In a particular aspect, a local memory  11  (such as non-volatile random access memory (RAM) and/or read-only memory (ROM), including for example one or more levels of cached memory) may also form part of CPU  12 . However, there are many different ways in which memory may be coupled to system  10 . Memory  11  may be used for a variety of purposes such as, for example, caching and/or storing data, programming instructions, and the like. It should be further appreciated that CPU  12  may be one of a variety of system-on-a-chip (SOC) type hardware that may include additional hardware such as memory or graphics processing chips, such as a QUALCOMM SNAPDRAGON™ or SAMSUNG EXYNOS™ CPU as are becoming increasingly common in the art, such as for use in mobile devices or integrated devices. 
     As used herein, the term “processor” is not limited merely to those integrated circuits referred to in the art as a processor, a mobile processor, or a microprocessor, but broadly refers to a microcontroller, a microcomputer, a programmable logic controller, an application-specific integrated circuit, and any other programmable circuit. 
     In one aspect, interfaces  15  are provided as network interface cards (NICs). Generally, NICs control the sending and receiving of data packets over a computer network; other types of interfaces  15  may for example support other peripherals used with computing device  10 . Among the interfaces that may be provided are Ethernet interfaces, frame relay interfaces, cable interfaces, DSL interfaces, token ring interfaces, graphics interfaces, and the like. In addition, various types of interfaces may be provided such as, for example, universal serial bus (USB), Serial, Ethernet, FIREWIRE™, THUNDERBOLT™, PCI, parallel, radio frequency (RF), BLUETOOTH™, near-field communications (e.g., using near-field magnetics), 802.11 (WiFi), frame relay, TCP/IP, ISDN, fast Ethernet interfaces, Gigabit Ethernet interfaces, Serial ATA (SATA) or external SATA (ESATA) interfaces, high-definition multimedia interface (HDMI), digital visual interface (DVI), analog or digital audio interfaces, asynchronous transfer mode (ATM) interfaces, high-speed serial interface (HSSI) interfaces, Point of Sale (POS) interfaces, fiber data distributed interfaces (FDDIs), and the like. Generally, such interfaces  15  may include physical ports appropriate for communication with appropriate media. In some cases, they may also include an independent processor (such as a dedicated audio or video processor, as is common in the art for high-fidelity A/V hardware interfaces) and, in some instances, volatile and/or non-volatile memory (e.g., RAM). 
     Although the system shown in  FIG.  20    illustrates one specific architecture for a computing device  10  for implementing one or more of the aspects described herein, it is by no means the only device architecture on which at least a portion of the features and techniques described herein may be implemented. For example, architectures having one or any number of processors  13  may be used, and such processors  13  may be present in a single device or distributed among any number of devices. In one aspect, a single processor  13  handles communications as well as routing computations, while in other aspects a separate dedicated communications processor may be provided. In various aspects, different types of features or functionalities may be implemented in a system according to the aspect that includes a client device (such as a tablet device or smartphone running client software) and server systems (such as a server system described in more detail below). 
     Regardless of network device configuration, the system of an aspect may employ one or more memories or memory modules (such as, for example, remote memory block  16  and local memory  11 ) configured to store data, program instructions for the general-purpose network operations, or other information relating to the functionality of the aspects described herein (or any combinations of the above). Program instructions may control execution of or comprise an operating system and/or one or more applications, for example. Memory  16  or memories  11 ,  16  may also be configured to store data structures, configuration data, encryption data, historical system operations information, or any other specific or generic non-program information described herein. 
     Because such information and program instructions may be employed to implement one or more systems or methods described herein, at least some network device aspects may include nontransitory machine-readable storage media, which, for example, may be configured or designed to store program instructions, state information, and the like for performing various operations described herein. Examples of such nontransitory machine-readable storage media include, but are not limited to, magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROM disks; magneto-optical media such as optical disks, and hardware devices that are specially configured to store and perform program instructions, such as read-only memory devices (ROM), flash memory (as is common in mobile devices and integrated systems), solid state drives (SSD) and “hybrid SSD” storage drives that may combine physical components of solid state and hard disk drives in a single hardware device (as are becoming increasingly common in the art with regard to personal computers), memristor memory, random access memory (RAM), and the like. It should be appreciated that such storage means may be integral and non-removable (such as RAM hardware modules that may be soldered onto a motherboard or otherwise integrated into an electronic device), or they may be removable such as swappable flash memory modules (such as “thumb drives” or other removable media designed for rapidly exchanging physical storage devices), “hot-swappable” hard disk drives or solid state drives, removable optical storage discs, or other such removable media, and that such integral and removable storage media may be utilized interchangeably. Examples of program instructions include both object code, such as may be produced by a compiler, machine code, such as may be produced by an assembler or a linker, byte code, such as may be generated by for example a JAVA™ compiler and may be executed using a Java virtual machine or equivalent, or files containing higher level code that may be executed by the computer using an interpreter (for example, scripts written in Python, Perl, Ruby, Groovy, or any other scripting language). 
     In some aspects, systems may be implemented on a standalone computing system. Referring now to  FIG.  21   , there is shown a block diagram depicting a typical exemplary architecture of one or more aspects or components thereof on a standalone computing system. Computing device  20  includes processors  21  that may run software that carry out one or more functions or applications of aspects, such as for example a client application  24 . Processors  21  may carry out computing instructions under control of an operating system  22  such as, for example, a version of MICROSOFT WINDOWS™ operating system, APPLE macOS™ or iOS™ operating systems, some variety of the Linux operating system, ANDROID™ operating system, or the like. In many cases, one or more shared services  23  may be operable in system  20 , and may be useful for providing common services to client applications  24 . Services  23  may for example be WINDOWS™ services, user-space common services in a Linux environment, or any other type of common service architecture used with operating system  21 . Input devices  28  may be of any type suitable for receiving user input, including for example a keyboard, touchscreen, microphone (for example, for voice input), mouse, touchpad, trackball, or any combination thereof. Output devices  27  may be of any type suitable for providing output to one or more users, whether remote or local to system  20 , and may include for example one or more screens for visual output, speakers, printers, or any combination thereof. Memory  25  may be random-access memory having any structure and architecture known in the art, for use by processors  21 , for example to run software. Storage devices  26  may be any magnetic, optical, mechanical, memristor, or electrical storage device for storage of data in digital form (such as those described above, referring to  FIG.  20   ). Examples of storage devices  26  include flash memory, magnetic hard drive, CD-ROM, and/or the like. 
     In some aspects, systems may be implemented on a distributed computing network, such as one having any number of clients and/or servers. Referring now to  FIG.  22   , there is shown a block diagram depicting an exemplary architecture  30  for implementing at least a portion of a system according to one aspect on a distributed computing network. According to the aspect, any number of clients  33  may be provided. Each client  33  may run software for implementing client-side portions of a system; clients may comprise a system  20  such as that illustrated in  FIG.  21   . In addition, any number of servers  32  may be provided for handling requests received from one or more clients  33 . Clients  33  and servers  32  may communicate with one another via one or more electronic networks  31 , which may be in various aspects any of the Internet, a wide area network, a mobile telephony network (such as CDMA or GSM cellular networks), a wireless network (such as WiFi, WiMAX, LTE, and so forth), or a local area network (or indeed any network topology known in the art; the aspect does not prefer any one network topology over any other). Networks  31  may be implemented using any known network protocols, including for example wired and/or wireless protocols. 
     In addition, in some aspects, servers  32  may call external services  37  when needed to obtain additional information, or to refer to additional data concerning a particular call. Communications with external services  37  may take place, for example, via one or more networks  31 . In various aspects, external services  37  may comprise web-enabled services or functionality related to or installed on the hardware device itself. For example, in one aspect where client applications  24  are implemented on a smartphone or other electronic device, client applications  24  may obtain information stored in a server system  32  in the cloud or on an external service  37  deployed on one or more of a particular enterprise&#39;s or user&#39;s premises. In addition to local storage on servers  32 , remote storage  38  may be accessible through the network(s)  31 . 
     In some aspects, clients  33  or servers  32  (or both) may make use of one or more specialized services or appliances that may be deployed locally or remotely across one or more networks  31 . For example, one or more databases  34  in either local or remote storage  38  may be used or referred to by one or more aspects. It should be understood by one having ordinary skill in the art that databases in storage  34  may be arranged in a wide variety of architectures and using a wide variety of data access and manipulation means. For example, in various aspects one or more databases in storage  34  may comprise a relational database system using a structured query language (SQL), while others may comprise an alternative data storage technology such as those referred to in the art as “NoSQL” (for example, HADOOP CASSANDRA™, GOOGLE BIGTABLE™, and so forth). In some aspects, variant database architectures such as column-oriented databases, in-memory databases, clustered databases, distributed databases, or even flat file data repositories may be used according to the aspect. It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular aspect described herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art. 
     Similarly, some aspects may make use of one or more security systems  36  and configuration systems  35 . Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with aspects without limitation, unless a specific security  36  or configuration system  35  or approach is specifically required by the description of any specific aspect. 
       FIG.  23    shows an exemplary overview of a computer system  40  as may be used in any of the various locations throughout the system. It is exemplary of any computer that may execute code to process data. Various modifications and changes may be made to computer system  40  without departing from the broader scope of the system and method disclosed herein. Central processor unit (CPU)  41  is connected to bus  42 , to which bus is also connected memory  43 , nonvolatile memory  44 , display  47 , input/output (I/O) unit  48 , and network interface card (NIC)  53 . I/O unit  48  may, typically, be connected to peripherals such as a keyboard  49 , pointing device  50 , hard disk  52 , real-time clock  51 , a camera  57 , and other peripheral devices. NIC  53  connects to network  54 , which may be the Internet or a local network, which local network may or may not have connections to the Internet. The system may be connected to other computing devices through the network via a router  55 , wireless local area network  56 , or any other network connection. Also shown as part of system  40  is power supply unit  45  connected, in this example, to a main alternating current (AC) supply  46 . Not shown are batteries that could be present, and many other devices and modifications that are well known but are not applicable to the specific novel functions of the current system and method disclosed herein. It should be appreciated that some or all components illustrated may be combined, such as in various integrated applications, for example Qualcomm or Samsung system-on-a-chip (SOC) devices, or whenever it may be appropriate to combine multiple capabilities or functions into a single hardware device (for instance, in mobile devices such as smartphones, video game consoles, in-vehicle computer systems such as navigation or multimedia systems in automobiles, or other integrated hardware devices). 
     In various aspects, functionality for implementing systems or methods of various aspects may be distributed among any number of client and/or server components. For example, various software modules may be implemented for performing various functions in connection with the system of any particular aspect, and such modules may be variously implemented to run on server and/or client components. 
     The skilled person will be aware of a range of possible modifications of the various aspects described above. Accordingly, the present invention is defined by the claims and their equivalents.
