`
`BACKGROUND
`
`Conventional telephone equipment is well known in the art, Telephone
`
`companies have devoted substantial time and money to add featuresto the
`conventional telephone suchas call waiting, caller-ID, voice-mail and so forth. While
`these features are beneficial, theystill use the central equipmentprovided by the
`
`telephone company and do not permit the user (e.g. a company)to integrate the
`features on their own. Asaresult, the user is limited by the choices offeatures to
`
`those offered by the telephone company,
`
`Accordingly, a limitation of conventional telephone networks is that the
`features available to the users are limited. What is needed is a telecommunications
`
`15
`
`processing apparatus and method that provides a wide range of features that the users
`can configure on their own,
`
`SUMMARY
`
`20
`
`Theinvention overcomesthe identified problems and provides an innovative
`
`telecommunicationsprocessing apparatus and method. The invention provides a
`
`numberofinnovative features that can be readily configured by the user.

`
`DETAILED DESCRIPTION
`
`Exemplary embodiments are described with reference to specific
`
`configurations. Thoseskilled in the art will appreciate that various changes and
`
`modifications can be made while remaining within the scope of the claims. For
`
`examiple, while the telecommunications networks referred to herein are Public
`
`15
`
`Switched Telephone Networks (PSTN) and the Internet, any communication network
`
`can be used.
`
`1.
`
`Conventional Telecommunications System
`
`Referring to Figure 1, aconventional telephone network includesan initiator
`
`20
`
`telephone 110, a Public Switched Telephone Network (PSTN) 120, an automatic call
`distributor 130 anda plurality of destination telephones 140, 150. The initiator 110
`picks up the receiver and initiates a telephonecall to a destination 140. Thecall is
`
`routed through the PSTN to the automatic call distributor 130, which can be a PBX.
`
`The automaticcall distributor directs the call to the destination 140, Ifthe destination
`
`25
`
`is not available, then the automatic call distributor either provides a busy signal to the
`initiator or re-directs the call to a voice mailbox system.
`

`
`Personal Based Telecommunications System
`
`30
`
`Figure 2 depicts a call waiter 200 according to an embodimentof the invention.
`Thecall waiter is coupled to the telecommunications network, whichin this case is a
`PSTN 120. While the PSTN 120 is shown as a wired system,in one aspect of the
`
`inventionit is implemented as a wireless system.

`Figure 3A shows a block diagram ofthe call waiter 200. A memory 210 is
`
`configured to store control procedures 212 for execution in the processor 220. The
`control procedures instruct the processor how to behave based on various conditions
`such as an incoming call, message, and other conditions. The memory also stores data
`
`214 that assists the processor in executing the contro] procedures and provides the
`
`processor with a location to store the caller profile data. Figure 3B shows an
`
`exemplary data structure 214 for a caller. This includesthe last name,first name,
`
`primary telephone number, primary telephone number, secondary telephone number,
`
`tertiary telephone number, status updates (Y/N), status updates,status update mode,
`
`10
`
`phone/e-mail/web/fax, language preference, marketing/advertising (Y/N), Disconnect
`
`after x minutes, and personal identification numbers (PIN).
`
`Referring to Figure 3C, a functional block diagram showsthe processor
`
`includes an analogor digital incoming line termination 230. The processor can
`
`perform caller authentication and caller profile maintenance 232. The processor can
`
`15
`
`also perform call holding and forwarding 234. Additionally, the processor includes an
`
`analog or digital outgoing line termination.
`
`Figure 4 is a flowchart 250 showing an exemplary operation of the call waiter
`
`of Figure 2. In step 252, the initiator places the call. In step 254, the call waiter
`
`determines whether a call is incoming. Step 256 authenticates the caller and step 258
`
`20
`
`allows the caller to make calls and to negotiate audio prompts. Step 260 determines
`
`whetherto initiate waiting. If not, the procedure is returned to step 258. If so, step
`
`262 plays a messageforthe destination,or operator. If the destination does not answer
`
`the telephone, step 264 returns the procedure to step 262. If the destination answers
`
`the telephone, step 266 forwards the call back to the initiator using the initiators
`
`25
`
`profile data.
`
`In an aspect ofthe invention, the system stores data 214 for each registered
`user. This data is used by the system to determinethe priority of telephone numbers to
`
`call, the status ofthe call-backs, the type ofcall back notification the registered user
`
`prefers as well as language preference, marketing preference, disconnect preference
`
`30
`
`and others. Since each ofthe users has a personal identification number (PIN), the
`
`users can each modify their respective information in a number of ways, One wayis
`
`bycalling a customer service representative and having them change the information.
`
`Another way is over the telephone using the PIN bypressing the keypad and then
`
`

`

`Case 6:22-cv-00031-ADA Document 43-18 Filed 07/19/22 Page 7 of 20

`
`WO 01/97494
`
`PCT/US01L/40927
`
`interacting with the system to modify or confirm the information. Still another way is
`
`over a network interface such as an Internet interface. This way, the user can call up a
`
`browser and interact with the system via the network, A personal computer browser
`
`such as Netscape or Microsoft can be used as well as a wireless browser such as one
`
`from Palm Computing, Phone.com or other vendor.
`
`By modifying the data, the user can make it convenient for both the caller and
`
`the destination. The destination person will return the call to the phone orother device
`
`where the user is most-likely located. For example, the user might prefer to be called
`
`on a cell phone and then switch over to a land phone. In one aspect of the invention,
`the data includes a parameter that identifies the time for which the system will call the
`
`10
`
`primary, secondary, tertiary or other number. For example, a user may want to be
`
`called during business hoursonly, or the user may prefer to be called one a cell phone
`
`or at home after business hours. In this case, the call is either disconnected or taken
`
`offthe queueonce those conditionsare satisfied. In another example, the user can
`
`15
`
`instruct the call waiter to make a predetermined numberofattempts (e.g. redials at
`
`predeterminedintervals) and then disconnector be taken off the queue,
`
`Thestatus of the call can be monitored by the system and reported to the user.
`
`For example, if the user wants to know at some predeterminedinterval of 10 minutes
`
`whattheir position in the queue, then the system will call the user at the predetermined
`
`20
`
`intervals and inform the user of that information. Additionally, other status can be
`
`reported such as message opened(e.g. voice-mail retrieved), call failure, non-
`
`availability of the destination or other status. In this manner, each user can go about
`
`their business while waiting for either the return call or a call informing them ofthe
`
`call status. This technique assists people in planningtheir time and activities. One
`
`25
`
`additional feature of the inventionis the ability of the system to incorporate
`
`advertising or marketing information into the call. This added benefit allows the
`
`businessto introduce extra services to the customers orcollect additional revenue from
`
`other companies. In even another aspect, the system administrator (e.g. owner) can
`
`offer the business a discounton service in exchange for delivering paid advertising to
`
`30
`
`customers.
`
`In another aspect of the invention, the parameter can be set to a specific
`
`numberofcall-backs before failing. Moreover, since the data includesa field for the
`
`preferred method ofnotification, e.g. by phone, e-mail, fax, etc., the system will try to
`

`reach the user in the way most-likely to succeedfor that particular user. Since users
`
`are different and may prefer different types ofnotification, the inventive system is
`optimized for each particular user. Finally, If there is a failure of the system to have
`the destination return thecall, the call waiter can send the failure notice to the user
`
`using the method bestfor the user. In one aspect of the invention, in case ofafailed
`call return, the system can give the user the option of leaving a messagefor the
`
`destination that describes the nature ofthe call.

`
`Figure 5 depicts a conventional telephone network coupled to a small business
`
`call distributor accordingto thepriorart for small business andis similar to Figure 1.
`
`Figure 6 depicts a call waiter for use with a small business distributor
`
`according to an embodimentof the invention. In this embodiment, a small business
`
`subscribes to the call waiter 200 services. The call waiter 200 assigns one or more
`
`telephone numbers to each of the business subscribers. When an initiatorcalls the
`
`business, the call waiter monitors the call and answers the telephoneif the destination
`
`is not available. As soon as the destination becomes available, the call waiter notifies
`
`the destination and placesacall to the initiator.

`
`Management System
`
`Figure 7 depicts a automatic call distributor 130 combined with a call waiter
`200 according to an embodimentof the invention, This system allowsthe automatic
`
`call distributor (ACD) to providethe initiator caller an option to hang-up and maintain
`the priority on the call queue, When the destination becomesavailable,the initiator is
`
`called back by the system andthe call is established between the destination and the
`
`initiator, Alternately, based on a preferenceofthe initiator, which can bestoredin the
`
`profile data, the call waiter switches from the automatic call distributor to an
`
`interactive voice system that can interface with a customerrelationship management
`
`30
`
`system. This capability allowsthe initiator to log into the call control customer center.
`
`The inventive system can integrate with customer services software and
`automatic call distribution software and customer relationship management (CRM)

`
`Combination With PSTN
`
`Figure 8 depicts a PSTN 220 combinedwith a call waiter according to an
`embodimentof the invention. In this embodiment, the call waiter service is provided
`
`on a subscription basis to customers. The PSTN is modified to include the call waiter
`
`services, much in the same way that telephone companies add services suchas call
`
`waiting. The sequenceof operationisslightly different in this embodiment in that
`
`10
`
`when the PSTN detects that the destination is not available through the automatic call
`
`distributor 120, the PSTN call waiter service is activated. Once the destination is
`
`available, the call is completed between the initiator and the destination. Alternately,
`the PSTN can allow theinitiator to store profile data and then establish a call between
`the destination and the initiator when the destination is available.
`
`6.
`
` Intemet Based Telecommunications Systems
`Figure 9 depicts a call waiter combined with an Intemet communications
`
`network according to an embodimentof the invention. It is anticipated that all the
`features and functions previously described are equally applicable to this embodiment,
`
`20
`
`for example, voice over IP, net-phone software or other technology that involves audio
`
`streaming over the Internet. In this embodiment, the initiator 110 is coupled to the
`
`Internet 420, and to an automatic call distributor 430 to a destination 440, 450, Ifthe
`
`call is made from the initiator 110 to the destination 430, then the call is handled much
`
`in the same way described above, but with the substitution of the Internet 420 as the
`
`25
`
`telecommunications network. In this case, a bridge 500 between the Internet 420 and
`
`the PSTN 120 can be providedto increasethe flexibility of calling between a
`
`destination 110 coupled to the Internet 420 and the destination 140 coupled to the
`
`PSTN 120. All other functions are similar to those described above with respectto the
`
`PSTN telecommunications network.
`
`30
`
`Figure 10 depicts a call waiter combined with an Internet communications
`network according to another embodimentof the invention. In this embodiment, a call
`
`waiter 200 is coupled to the Intemet 420 to provide call waiter functions between an
`
`initiator 110 and a potential destination 140, 150, 440, 450. The call waiter 200

`
`performs the same functions overthe Internet 420 as those described above with
`
`respect to the PSTN network.
`
`7.
`
`Call Waiter Administration
`
`One feature ofthe call waiter is the administration function. Thatis, the ability
`
`to set up and control the various features and functions. In many circumstances,all the
`described features will be desired, and in other circumstances, a specific set of the
`
`described features will be desired. The administration function allows the system
`ownerto configure the system and even allow the users to configureselect portions of
`
`the system.
`In one aspect ofthe invention, the system administration is handled be a user
`interface directly coupled to the call waiter. Such an interface can be a laptop
`
`computer, a dedicated terminalor other interface. In anotheraspectofthe invention,
`the system administration is handled over a network, for example the Internet. The
`
`system administrator calls up a predetermined web page using a browser and then
`
`proceedsto set the various features, functions and parameters for the system. The
`
`system can be configured to store a database of users, or to access a database at a
`
`different location over the network. In yet another aspect of the invention, the users
`are allowed to log into the system and modify their respective data fields using their
`
`respective PIN. Theuser interaction with the system can accessed by audio over a
`
`telephone or through a computer network such as the Internet.
`
