2318703 SYSTEM FOR INTERACTrVE CONTROL OF CONTUTER AND TELEPHONE

Field of the Invention 5

This invention relates in general to personal computers and telephony, and more particularly to an interactive system by which a computer and telephone function cooperatively to implement a multiplicity of functions invoked by a user.

Bachmund of the Invention Software applications are known in the art for implementing telephony features using a personal computer. According to existing First Party Call Control architectures, a physical connection is provided between the telephone and personal computer for providing Computer Telephony Integration (Cp. Such prior art CII architectures have suffered from extreme limitations in functionality and ease of use.

For example, in order to place a phone call, a user typically must first close or minimize whatever application he or she is currently running (eg. Nficrosoft Words), open the CTI application, enter the digits to be dialled via point-and- click numbers, and then click an accept or dial button. Alternatively, according to some CII architectures, the user is able to navigate or browse a telephone dire=ry in order to identify the party to be called and ther4 once located, highlight the party's name and click a dial button.

Understandably, the awkwardness of using such systems and the limited features provided thereby have led some consumers to abandon prior art C71 systems in favour of more functional telephone sets or even "plain old telephone sets" (POTS) with enhanced features being provided by the central office.

One of the reasons for the awkwardness and limited functionality of prior art

CII architectures is that there is no seamless integration of functions activated by the telephone and functions activated directly or indirectly by the computer.

Recent developments in the standardization of computer interfaces have led to 2 increased development of software applications which are adapted to integrate functionality of a personal computer with various and diverse external devices. For example, the recently established standard for USB (Universal Serial Bus - a 12 Mbit/s serial interface running over a four wire bus. with an associated software stack supporting peripheral connectivity to a personal computer) is expected to yield a raft of software applications which interact cooperatively with external devices ranging from video games to faxes and data modems.

An object of the present invention is to provide an interactive telephone and PC-based software application which will overcome the limitations of prior art C71 architectures and be compatible with emerging standardized interfaces such as USB.

Turning to Figure 1, the computer-based telephony system of the present invention is shown in its broadest aspect comprising a telephone set 1 connected to a telephone switching system 3 (e.g. central office) via a telephone line 5. The telephone set 1 is also connected to a personal computer 7 via a serial link 9. lle personal computer 7 includes a monitor or display 8 as well as a mouse pointer 10 and keyboard 12, in a well known manner. According to the preferred embodiment, the serial link is one of either a USB or RS-232 line, although other suitable data communication links are possible. lle computer 7 executes a TAPI compliant software application for communicating with the telephone set 1 to implement various telephony functions, as discussed in greater detail below.

The telephone set 1 includes a handset 11 and keypad 13, and in addition is includes a plurality of programmable function keys 15. As discussed in greater detail below, respective ones of the function keys may be progmmmed via the soft application executed on computer 7 to activate predetermined telephony fimctions or so functions on the computer. For example, in one scenario a function key may be programmed to automatically activate a "Do Not DisturV feat= while in another scenario the ftmction key may be programmed to launch a software application such as Nficrosoft WordID. The set 1 also includes a message waiting lamp 16 which is activated by the software application to notify the caller of an incoming message, which can be a voic message, a fax, Internet email or other multimedia message.

As indicated above, the software application running on computer 7 communicates with telephone set 1 via serial link 9. As shown in Figure 2, in order for this communication to take place, data must pass through a plurality of modules which form a protocol stack between the application 17 and telephone set 1. 1he telephone set 1 incorporates a microprocessor 19 (e.g. Intel 80930) with Flash EPROM memory 2 1. A modem 23 is connected to microprocessor 19 and is also provided with a Flash memory 25. The microprocessor 19 and modem 23 together control implementation of standard telephony functions such as incoming call, 9 outgoing call, call waiting, speaker phone conversation, hold, etc., in a well known manner. However, in accordance with the principles of the present invention, the software application 17 is able to interact with the telephone set 1 to cooperatively implement a multiplicity of user-invoked features.

Although the software modules comprising the protocol stack do not form part of the present invention, a brief description is provided herein for completeness. The highest level in the stack is represented by the software application 17 which comprises a plurality of user interface components for display and printing fl=tionality, as discussed in greater detail below with reference to Figure 9.

Immediately below the application 17 is a core 27 comprising a plurality of engine components for providing all of the support which the user interface components require to display and print data. This support includes call processing, data storage and manipulation, application configuration management and audio recording and is playback. The engine components are located in one or more DLLs with "C" language interfaces to them, as discussed in greater detail below.

According to the preferred embodiment as of the filing date of this application, the application 17 is coded in VisualBasic wh=as the core 27 of engine components is coded in C++. To facilitate access from VisualBasic to the DLLs, an OCX layer 29 is provided. The OCX layer 29 is also coded in C++.

Below the OCX layer is TAPI layer 3 1, which is a Nficrosoft device independent communication library created by Nficrosoft for use by programmers writing telephony applications (including data, fax and voice modem) for Nficrosoft operating systems.

Below TAPI layer 31 is a TAPI service provider referred to as "Musindm.Tsp" layer 33. This layer communicates with Nficrosoft's "Unimodem1V.Tsp" and "Unimodem/V.Vxd" layers 35 and 37, respectively, which form the standard Windows 95C low-level so architecture for supporting telephony applications utilizing voiceldatalfax modem.

The "Unirnodem/V.Vxd" layer 3 7 communicates with a MiteiNxd layer 3 9 which provides an interface to the standard VCOM layer 4 1. VCOM layer 41 is a static VxD which is loaded when booting Windows 95, and which functions as a device driver interface to the devices connected to serial link 9 (ie. USB or RS-232 port drivers).

Since the UniModem V architecture does not support a number of essential telephony signals, such as keypad, hookswitch, hold, etc., a 16 bit/32 bit "thunking layer" 43 is provided for circumventing the UniModem V layers for these signals.

At the lowest levels of the protocol stack VCOM layer 41 communicates with one of either with a VCOM mapper 45 for the USB version of this invention or a VCOM port driver referred to as MSeriaiNxd 47.

is For the USB version, VCOM mapper 45 communicates with a USB device driver "musb.sys" 49 for causing the USB to "appeae' as a serial port. The ".rnusb.sys" driver 49 communicates the standard Nficrosoft USB stack and associated hardware 5 1 for trattsmitting and receiving serial data via the USB.

For the RS-232 version, the MSeriaLVxd driver 47 communicates with a UART 53 (Universal Asynchronous Receiver Transmitter) in a well known manner.

At the telephone set 1, the USB hardware 5 1 communicates di=tiy with microprocessor 19 via associated USB hardware incorporated into the microprocessor, whemas for the RS-232 version UART 53 communicates with a fluther UART 55 connected to the microprocessor 19.

As indicated above, the user interface components of application 17 are responsible for implementing a Graphical User Interface (GUI) which allows the user to access various so and telephony features. The principal user interface to these features is provided by the main window 57 which is depicted via display 8 of computer 7. Two embodiments of the GUI are discussed herein. A first embodiment 11 is initially shown in Figure 3 while an alternative embodiment is initially shown in Figure 5. The basic user functionality provided by the two embodiments is similar. A detailed description of the functionality is described herein in detail with reference to the first embodiment, and supplemented where appropriate with reference to the alternative embodiment. As of the date of initial filing of this application, the second embodiment constitutes the best mode, the operation of which will be understood by a person of ordinary skill in the art having reference to the detailed description of the first embodiment supplemented by reference to the second embodiment disclosed herein.

The main window display according to the first embodiment (Figure 3), includes a title bar 59 with document control menu icon as well as minimize and close buttons, a customizable toolbar 60 with volume, speaker, microphone, voicemail.

profile, phonebook, call log and help buttons showing, a display area 61 with name field, num field and call state information, a context sensitive default button 63 which has focus and responds to the "Enter" key from the keyboard of computer 7 (unless the focus is changed by the user), a control bar actuator 65, a menu bar 67, resize control 69, and a status line 71 with indicators including receptionist icon 73, voicemad icon 75 and "Do Not DisturV icon 77.

A horizontal control bar 79 can be opened from the main window display 5 7, as shown in Figure 4. Ile control bar 79 opens when the screen pointer of mouse 10 passes over the control bar actuator 65 (similar to the auto hidelshow feature of the Windows 954P task bar), and can be programed to open automatically in the event of an incoming caU at telephone 1. According to one embodiment of the invention a time delay is provided (e.g. 0.2 secs) after positioning the mouse pointer over the actuator 65, in order to prevent accidental inadvertent opening of the control bar 79. The control bar 79 remains open as long as mouse pointer 10 is positioned over any one of the function buttons 8 1. Prekrably, a time delay is provided (e.g. 0.5 secs. ) after the 30 mouse pointer 10 has moved from the control bar 79 before the control bar is closecl The control bar 79 may also be opened using a keyboard sequence (such as Alt+m).

12 In the event that the user drags the main window display 57 to the right side of display 8 so that there is no longer sufficient room for the control bar 79 to open to the right, the control bar and associated default button 63 swap positions with the display area 61 and the control bar opens to the left of the main window display 57.

This feature of the invention is shown in Figure 5b and Sc, which show the main window display 57 according to the alternative embodiment.

The control bar 79 provides a normally hidden menu of function buttons 81 to the user. The buttons 81 are preferably labelled with icons and text By keeping the control bar 79 closed during normal operation, considerable screen real estate is saved. Opening of the control bar 79 provides the user with immediate access to call handling features without having to scroll through a multitude of menus or buttons, waiting for tool tips to pop-up, etc., as is common with prior art CTI applications.

Furthermore, according to an important aspect of the invention, the default button 63 and buttons 8 1 of the control bar 79 are context sensitive so as to provide functionality derived from all parts of the so application 17, but only function options which are appropriate to the state of the telephone call (e.g. when a call is in progress, as shown in Figure 4, the options are Hang Up, Hold, Recorder and Open File).

According to the embodiment shown in Figure 3, the options of menu bar 67 include:

1) a File menu for providing access to Import and Export ftmetions; (e.g. links to contact fists from other PMs, etc.), and an Exit command which quits the application 17; ii) an Edit menu which provides access to well known cut, copy, paste and delete commands, which may be used to modify both the name and number fields of display are 6 1; iii) a View menu which allows the user to hide or show the toolbar 60 within main window 57; iv) a Phone menu for presenting various telephony function options to the 13 user for call handling - as with the default button 63 and function buttons 81 discussed above, the telephony function options presented in the Phone menu are made context sensitive by dimming commands which are not appropriate to the telephone call state; v) a Dial menu which presents the user with a list of user definable important or frequently dialled numbe as well as a Calls Made list and Calls Received list -the Dial menu including:

- a Speed Dial sub-menu defined by the user in the phonebook such that for each person in the list, all relevant phone numbers are displayed. Upon selection of a phone number, the name and number are dropped in display area 6 1, the telephone 1 goes og-hook and digits are immediately out-pulsed; - a Calls Made sub-menu for providing the user with a list of the last 20 people who were called, sorted by date and time, with the last person called appearing at the top of the fist; a Calls Received sub-menu for providing the user with a list of the last 20 people who called, sorted by date and time.

vi) a Tools menu 74 (see Figure 25a) for providing the user with access to advanced features of the application 17, such as:

- a Phonebook sub-menu for providing the user with access to various phonebook fimctions and directories; - a Messages sub-menu for providing the user with access to sg fimctions, greetings as well as voicemail messages left for the user in the Call Log (discussed below); - a Call Log sub-menu which opens the user's call log, (discussed below); - a Call Screening menu the call screening function on or off (i.e. sending incoming calls, except those in the Call Screen folder of the phonebook, to voicemail without disturbing the user, - a Recorder menu item for opening the Recorder window for recording a conversation; - a Diallers sub-menu for providing a list of user defined buttons which can be used for speed-dialling or navigation (discussed in greater detail below).

14 The options of Menu bar 67 according to the embodiment of Figure 5 are similar, except that there are no View and Dial menu items.

As indicated above, and as shown in Figures 6a to 6c, the status line 71 includes a receptionist icon 73 for indicating that the receptionist fimction is active, meaning that advisory messages and personal messages are automatically played for specific callers based on CLID. As shown in Figure 6b, when the mouse pointer 10 enters the bounding box of receptionist icon 73, a tool tip box 78 opens displaying the current message to be played for incoming callers who are sent to voicemail. A right mouse button click when the mouse pointer 10 is over the receptionist icon 73 opens a shortcut menu 80 for selecting advisory messages, as shown in Figure 6c.

In the alternative embodiment shown in Figures 5a through 5c, the receptionist icon 73 appears as a button for implementing predetermined features such as call is screening, call blocking, greetings and personal messages, all of which are discussed in greater detail below.

Ile status line 71 also includes a voicemail icon 75 which f=tions as a messages indicator to alert the user to any new voicemail messages. As shown in Figures 7a to 7c, when messages are waiting the icon flashes (Figure 7a). As shown in Fig= 7b, when the mouse pointer 10 enters the bounding box of voicemail icon 75, a tool tip box 82 opens displaying the nurn of new messages. A right mouse button click when the mouse pointer 10 is over the voicernail icon 73 opens a shortcut menu 84 for accessing voicernail messagm as shown in Figure 7c. A double click opens the voicernail folder of the Call Log, as discussed in greater detail below.

A "Do Not DisturW' icon 77 is included in the status line 71, as shown in detail with reference to Figures 8a to 8d. The "Do Not DisturV icon 77 alerts the user that some or all callers are being prevented from calling in (see Figure 8a).

As shown m Fig= 8b, when the mouse pointer 10 enters the bounding box of "Do Not Disturb" icon 77, a tool tip box 86 opens displaying the status of Call Screen. A right mouse button click when the mouse pointer 10 is over the voicernail icon 73 opens a shortcut menu 88 for turning the Call Screen function on or off, as shown in Figure 8c, while a double click toggles between the onloff states. Figure 8d shows the icon 77 indicating that Call Screen is off In the alternative embodiment of Figure 5, a bell icon 72 is provided for opening a sound manager window for creating or changing sounds and assigning predetermined sounds to different functions, as discussed in greater detail below. Turning now to Figure 9, the user interface components of software

application 17 and the engine components of core 27 are shown in greater detail. All communications between the engine components and the user interface components are provided through a main window component 83. The main window component 83 displays the main window display 57 including menu bar 67, toolbar 60, status line 71, display area 61 and default button 63, as discussed above. If the data being communicated by the core 27 is intended for a user interface component other than the main window component 83, the main window component routes it appropriately.

A display window component 85 functions in conjunction with the window component 83 to generate display area 61 for showing line and call information.

Flyout menu component 87 displays the context-sensitive control bar 79 for providing push-button-style menu selections.

The application configuration dialog 89 and phone configuration dialog 9 1, in combination allow the user to configure the software application, as discussed in g detail below with reference to Figure 27.

The group editor 93 allows the user to manipulate entries in a Call Scree g list Call Blocking List or Speed Dial list as discussed in greater detail below.

Home - Name and home address Work - Name, company name, type of contact and business address Phone Numbers - Home, business, fax and cellular phone numbers Personal - User selectable greeting and message preferences Notes - Editor OCX that supports sound objects Shortcuts - Window with preferred application icons (e.g. Microsoft WordOD, ExcelC, etc.) which are automatically opened when the contact is called or when the contact calls 1 The user can configure programmable icons using the programmable icons dialog 97. Thew icons can be programmed to access CO voicemail and WR systems.

is The voice record dialog 99 allows the user to record greetings and other voice recordings.

The retrieve voicemail dialog 10 1 is used to access voicemail messages.

The call log 103 is used to display all telecommunications activity from the appUcation 17.

Ite about box 105 displays application version information and current system statistics, in a conventional manner.

When the user wishes to play a voice mail message from Nficrosoft ExchangeOD, a Microsoft Exchange UI application 107 is invoked. (user interface). This application displays controls to play, stop, rewind and fast forward the message. 30 The tray icon 109 appears in the Windows 950 task bar. When this icon is selected, the tray window is displayed. The tray window provides access to basic 17 functions of the application 17.

Turning now to the engine components of core 27, call manager 111 maintains call-specific data for all existing calls on all lines. The call manager 111 uses TAPI to obtain the call-specific information it requires. For each call, the following data is stored:

1 - TAPI call handle 2. call state 3. whether the call is incoming or outgoing 4. whether the call should be blocked (for incoming calls) 5. whether the call should be screened (for incoming calls) 6. digits dialled, name of person called (for outgoing calls) 7. caller ID number and name (for incoming calls) is 8. call start time, call duration 9. DW digits received (for incoming calls) Ile line manager 113 maintains line-specific data for all available telephone lines. It interfaces to TAPI 31 to perform line-related requests. The line manager facilitates multi-line support in the application 17. For each line, it stores the following data.

1. TAPI line handle 2. line state 3. feat= supported by the line 4. count of rings for an unanswered incoming call 5. existing calls on the line (actual data is maintained by call manager 111) 6. number of rings to wait before answering incoming calls 7. voice mail onloff state Line manager 133 also performs the following line-related requests:

18 1. dial number 2. hang up 3. answer incoming call The line manager 113 contains a TAPI callback to receive line-specific notifications from TAPI layer 3 1.

The phone manager 115 maintains data that is specific to the telephone 1. It interfaces to TAPI layer 31 to perform phone-related requests. The data maintained by phone manager 115 includes:

1. s of lamp 16 2. hookswitch status 3. phone button data is The phone manager 115 also contains a TAPI callback to receive telephone specific notifications from TAPI layer 3 1.

During operation, the telephone 1 needs to know when the application 17 is active. When the application is not active, the telephone 1 reverts to a regular POTS telephone and the programmable buttons 15 lose their flinctionality. In order to determine whether the application 17 is active, the telephone 1 attempts to send a so called 'are you alive?' message to the phone manager 115. The phone manager then responds with the appropriate reply.

19 The database manager 119 provides an interface to the databases 120 stored on disk in computer 7. The databases 120 are preferably stored in Microsoft Jet format (.MDB). This manager's interface is independent of the database technology being used. The database manager 119 supports the following functionality: 5 1. open and close databases 2. read and write database table data 3. perform database queries The smart data access manager 121 provides intelligent access and modification capabilities to all data required by the engine components of core 27 (excluding user preference data). For simplicity, the user interface components of application 17 may implement the data access functionality they require. For the best mode of this invention as of its filing date, the user interface components are written is in VisualBasict, so that the task of implementing data access functionality required is lified and results in saving the overhead of passing large amounts of data between the database and the engine components and then between the engine components and the user interface components. lle smart data access manager 121 uses the database manager 119 to read and write data that is stored in the databases 120.

The smart data access manager 121 supports the following functionality (or the subset of this functionality that only the engine components require):

1. read/write call log data a. get Last Number Redial, list b. get Calls Answered list C. get Cads Missed list 2. write Phonebook data 3. write voice mail data 4. read/write greeting message data 5. mad/write programmable icon data All required queries (known in advance), are understood by the smart data access manager 12 1. Ms manager is responsible for keeping track of data storage mechanisms in use by the application 17. All audio recordings (e.g. greeting messages and voice mail messages) are stored as separate disk files. References to these files are stored in the databases 120 where needed.

The call discrimination manager 123 is responsible for determining the call type (voice, fax or data modem) of incoming calls, by means of fax tone detection, distinctive ring, caller ID and DTW detection. The call control manager 117 passes any required call-specific information to the call discrimination manager 123 as it becomes available. Once an incoming call has be= discriminated, the call discrimination manager 123 informs the call control manager of the result. If the call is a fax or data modem call, the call control manager 117 attempts to pass it to an application that can handle it (using the phone manager 115).

is The registry manager 125 provides an interface to the Windows 959 registry.

lle configura#on manager 127 is responsible for maintaining application configuration information and user preferences on the basis of user input via the application configuration dialog 89 and phone configuration dialog 9 1. The configuration manager 127 uses the registry manager 125 to read and write the actual data.

The audio conversion manager 129 supports conversion between the native audio format (ADPCNI) and the WAVE audio format The native audio format will be used for recording and playback performed by the application 17. Audio files given to or obtained from other applications will be in the WAVE audio format.

The audio I/0 manager 131 is responsible for audio file input and output. It understands the native format used internally for play and record operations.

The media message control manager 133 is responsible for:

21 1. recording and playing greeting messages II. recording and playing voice mail messages IR. playing the phone ringing sound The call control manager 117 notifies the media message control manager 13 3 when any of the above functions need to be performed.

lle dialling manager 135 is responsible for processing all dialling requests including making calls from the Phonebook, the Last Number Redial list and the Speed Dial list It also keeps track of all required phone company dialling sequences (e.g. 3-way calling and call waiting).

The remote retrieval manager 137 is in charge of providing all functionality that can be accessed remotely. This ftmctionality consists of..

Is I. playing, saving and deleting voice messages, fl. modifying a greeting message According to one embodiment of the invention, the date and time that a voice me was received may be made available remotely, utilizing a text to speech OCX The voice mail manager 139 is responsible for playing previously recorded voice mail messages locally, either to the handset 11 or to a speaker device. This manager uses the smart data access manager 121 to get voice mail message file names and the media me control manager 133 to play the messages to the appropriate device.

The Nficrosoft Exchanget manager 141 provides an intertuce to all Nficrosoft Exchange& ftmetionality required by the application 17. In order for all voice mail messages to appear in the Nficrosoft ExchangeC Inbox, this manager adds a message to the Inbox folder of the user's message store for each voice mail message received.

22 As well, when the user wishes to play a voice mail message from Microsoft ExchangeO, a form application is invoked (as discussed in greater detail herein having regard to the Microsoft Exchange UI application 107 which displays controls to play, stop, rewind and fast forward the message).

Since voice mail messages can be played both from the application 17 and from Microsoft Exchanget, these two applications are synchronized in terms of played and deleted messages. If the Phonebook entries of application 17 are to appear in the user's default Microsoft Exchange& address book, the Microsoft Exchange(& manager 141 ensures that the Phonebook and address book are kept in sync.

In order to better understand how the application 17 and engine components of core 27 function, several call scenarios are described herein below with reference to the first embodiment of the invention, although an understanding of the second is embodiment will also be obtained therefrom.

A. Incoming Call When an incoming call is received, TAPIDLL 31 sends a message to the line manager 113 for each ring. This notification is forwarded to the call control manager 117. On the first rin& the line manager 113 creates a new call object using the call manager 111 and the call control manager 117 notifies the main window component 83 of the incoming call. In response, the main window 57 displays the incoming call status as shown in Figure 1 Oa wherein default button 63 displays a flashing bell icon.

In Figure 1 Ob, the control bar 79 is shown in the open position for displaying various call answer options (other than the default option provided by button 63), while in Figure 10c the same options are displayed via the phone menu item of menu bar 67.

With each ring event, the call control manager 117 causes the media message control manager 133 to play a "phone ringing" sound to the appropriate local er device. If a "caller ID data received" notification is received by the line manager 113, the line manager asks the call manager 111 to store the caUer ID data with the call's 23 object. The call control manager 117 then forwards the information to the call discrimination manager 123 and the main window component 83. The main window component 83 and the directory component 95 search the Phonebook directory for a match in stored telephone number with the identified telephone number of the calling party. In the event of no match being found, the unaltered CLID data is displayed in display area 61 (i.e. caller narne and telephone number). In the event of a match, the caller's name and telephone number are displayed in display area 61 of main window 57. According to the alternative embodiment, the user's image may also be displayed as shown in Figure 10d.

The call control manager 117 uses the smart data access manager 121 to determine if the call should be blocked or screenedL The resulting information is stored in the call's object If the call is to be blocked, the call control manager 117 either hangs up on the caller or sends the call to voice mail.

is If distinctive ring data is received by the line manager 113, it is stored in the call object and forwarded to the call discrimination manager 123.

With each ring event, the line manager 113 asks TAPI 3 1 for the answer ring count for the given line. If voice mail is turned on (which is determined from the configuration manager 127), after the required number of rinp have occurred, the line manager 113 arm= the call. The call control manager 117 then sends the call to voice mail, and forwards the information to the main window component 83 for display via display a= 61 of main window 57, as shown in Figures 11 a, 11 b and 11 c (wherein reference number 143 represents the Phone menu choice display from menu bar 67).

If a call is sent to voice mail, the call control manager 117 gets the file name of the greeting to be played to the caller from the smart data access manager 12 1.

This can be done using caller ID. The call control manager 117 also obtains the name of a file to which the voice mail message can be saved. The two file names are then passed to the media message control manager 133. This manager first plays the 24 greeting to the appropriate line device. Once the greeting playback has finished, it plays a "beep tone" sound to the line device. Once this sound has finished playing, recording starts. When recording has finished, the call control manager 117 asks the media message control manager 133 to stop recording. At this point, the call control manager 117 sends the voice mail message data to the smart data access manager 121 which stores it, and the phone manager 115 causes the lamp 16 to flash at telephone set 1.

If the user has fax so running on computer 7, the phone manager 115 causes lamp 16 to flash upon receipt of an incoming fax. Simikirly, it is contemplated that the lamp 16 may be caused to flash upon receipt of an incoming email message, or any multimedia message received via the computer 7.

If the user picks up the telephone handset or depresses the default button 63 while the call is in voice mail (Figure 12a), the call is taken out of voice mail and put in conversation mode (Figure 12b). If a voice mail message was in the process of being recorded, the voice mail data is sent to the smart data access manager 12 1.

if the user requests to divert the call to "Hold" and play the "Please Wait" message (e.g. by depressing the "HoW function button 81 (Figure 1 Ob)), the call control manager 117 asks the line manager 113 to put the call on hold. Then the call control manager 117 sends a request to the media message control manager 13 3 to playthe"Ple WaX' message. The call control manager 117 also send this information to main window component 83 which causes the icon 144 for default button 61 to change to "Retrieve from Hold" (Fig= 13) and to display an "On Hold" message and hold timer 145.

When the user hangs-up the handset 11 or prewes the "Hang Up" icon in default button 61 to complete the call (Figure 14a), call control call manager 117 advises main window component 83 which generates a "Hanging Up" me 147 in display area 61 (Figure 14b), and also retrieves the call data from the line manager 113 and passes it to the smart data access manager 121 which creates a call log entry (described in greater detail below). Tlen the call object is deleted and call control manager 117 advises window component 8 3 which displays the idle state of window 57 with a "Your Line is Free" message 149 in display area 61 (Figure 14c).

B. Outgoing Call Outgoing calls can be initiated in a number of ways, such as direct dial, store and dial, look-up name, speed dial and drag & drop name into the name field of display area 6 1, as discussed in greater detail below.

The user can dial directly from the telephone set 1 by either first picking up the handset 11 or pressing a speaker key to obtain dial tone and then dialling the phone number normally via the keypad 13. The user can also directly dial from application 17, as shown in Figures 1 Sa to 1 5d. From the idle state (Figure 1 5a), the is user clicks the "Make a Call" icon displayed in default button 63. In response, the main window component 83 sends a request to the dialling manager 135 to select a line. Upon selecting the line, dial tone is generated for the user and the call control manager 117 sends a message to main window component 83 for causing a cursor to flash in the "Number" field 15 1 of display area 61 (Figure 1 5b).

As digits are entered from the keypad 13 or keyboard 12 (Figure 1 5c), DTWT tones are generated and the dialling man,, er 135 constructs the relevant dial string and then asks the line manager 113 for a dialling prefix. If the user wishes to make a private call, the appropriate dialling characters are inserted into the dial string. If the digits entered match a Phonebook entry, the name of the person being called is displayed in the 'Name" field 153 of display area 61 and the caU timer 155 is displayed (Figure 1 5d). The dial string (and, if known, the name of the person being called) is then passed to the line manager 113 which creates a call object and initiates the call.

The user can also enter a phone number while on-hook, before out-pulsing the digits, as shown in Figures 16a to 16e. From the idle state (Figure 16a), the user 26 "clicks" the Number field 15 1. The cursor then flashes in the Number field 15 1 and the user begins entering digits (Figure 16b). As digits are entered, if a match is found in the Phonebook, the name of the person being called is displayed in the Name field

153 (Figure 16c) along with any label associated with the number (e.g. "Home", $'.Office"). Then the user clicks the "Make a Call" icon appearing in default button 63 or hits the "Entee' key since the default button 63 is in "focus", in response to which the line is selected and the digits are out-pulsed (Figure 16d), via appropriate interaction between line manager 113 and dialling mana er 135, as discussed above.

After dialling has been completed, the call timer 15 5 is displayed (Figure 16e).

The user can look-up a person by name without having to open the Phonebook. This calling sequence is shown in Figures 17a to 17L From the idle state (Figure 17a), the user "clicks" the Name field 153. The cursor then flashes in the.

Name field 153 and the user begins entering letters of the name of the person to be is called (Figure 17b). As letters are entered, the Phonebook is searched for matching names, the "found" portion of a matched name is then highlighted in the Name field

153, and a default phone number for the entry is displayed in the Number field 151 (Figure 17c). The user can select a different phone number for the person being called, from a drop-down list 157 activated by clicking on the down arrow at the right of the Number field 151 (Figure 17d). Once the desired num is selected and displayed in the Number field 151 (Figure 17e), the user clicks the "Make a Call" icon in default button 63 or hits the "Entee' key to select the line and begin digit out pulsing as described above. After dialling has been completed, the call timer 155 is displayed (Figure 171).

Using speed dial, a user can quickly access a list of important or finuently called persons, without having to search the Phonebook, as shown in Figures 1 ga, to 18d. From the idle state (Figure 18a), the user selects the "Dial "menu item from menu bar 67. From the "Speed Diar'list (Figure 18b), a name and preferred number are selected. The selected name and number are displayed (Figure 18c), a line is selected and out-pulsing begins as described above, and the default button 63 changes its icon to "Hang Up". Once the dialling is complete, the call timer 155 starts (Figure 27 18d).

According to another feature of the present invention, the user can drag and drop (i.e. cut and paste) text from another application in order to make a call or perform a search. Thus, from the idle state (Figure 19a), the user can highlight a portion of text 159 (usually a person's name) from another application which supports drag and drop functionality (e.g. word processor, spreadsheet, Microsoft ExchangelD, etc.), and drag the text out of the application and into window 57. As the user drags the text over the Name field 153, a drop symbol 161 appears under the mouse pointer (Figure 19b). Upon dropping the text in the Name field 153, the Phonebook is automatically searched and in response to a match the default number associated with the matched name is displayed in the Number field 15 1 (Figure 19c). By clicking on the default button 63 or hitting the "Enter" key, a line is selected and digit out-pulsing begins as described above (Figure 19d). Once the dialling is complete, the call timer is 155 starts (Figure 19e).

Once the user has completed the call, the handset 11 can be returned to its cradle or the user can press the speaker key on telephone set 1. Ite user can also hang-up from main window 57 by clicking on the "Hang Up" icon of default button 63 or hitting the "Entee' key (Figure 20a). While disconnecting, the line status displays the "Hangin Up' message 147 (Figure 20b), and finally the display r eturns to te idle state (Figure 20c). Meanwhile, the call control manager 117 gets the call data from the line manager 113 and passes itto the sm., data access manager 121 which creates; a caR log entry. Then the call object is deletecL C. Conversation Modes When the user is in a conversation with another party, the call can be in the foRowing states:

I. handset conversation R. speaker phone conversation 28 III. on hold When the user wishes to switch between conversation modes, the ain window component 83 sends a request to the call control mana er 117. The call control manager forwards the request to the line manager 113 which updates the call object's call state to the appropriate conversation mode.

D. Central Office 3-Way Call When the user wishes to initiate a 3-way call, the main window manager 83 sends a request to the g manager 13 5. The connection with the first party is established as described in the "Outgoing call" section appearing above. When the required call progress event(s) are received by the call control manager 117, the call control manager obtains the dial string required to call the third party from the dialling manager 13 5 and requests the line er 113 to dial. When the next required call progress event(s) are received, the call control manager 117 obtains the dial sting required to connect the three parties and sends it to the line manager 113 for dialling.

E. Call Waiting The main window manager 83 sends requests to switch between calls to the diallin manager 135. The didling manager then sends the appropriate dials to the call control mmager 117 which fbrwards them to the line manager 113 for F. Extension In Use Detection According to another aspect of the present invention, if another extension on the line with which the application 17 is associated is taken oIT-hook, the phone manager 115 is informed. In response, the phone manager notifies the call control manager 117 which modifies the line's state using the line manager 113 and forward 29 the notification to the main window manager 83. The main window manager then causes the main window to display an in use state indicator in display area 6 1, as shown in Figure 2 1.

G. Adding a Person to Phonebook and Opening Profile The user can add a caller or called party to the Phonebook, including CLID information. From the connected state (Figure 22a), the user rolls the mouse pointer over the control bar actuator 65 (or, alternatively enters Alt + M on the keyboard 12), which causes the control bar 79 to appear (Figure 22b). The user then clicks on the "Add to PhonebooC icon in function button 8 1, which causes the Phonebook window 163 to open to a'New Entries" display (Figure 22c), thereby presenting the user with a list of new entries including the entry for the connected party 165 which is highlighted. The 'New Entries" display is indicated as being open at the directories is display appearing on the left side of window 163.7he main window 57 remains in the background.

WIthin the Phonebook window 163, the user can move or make copies of entries by dragging entries from one list to another using the mouse pointer 10, or can search for entries using a "Find" command in the Tools menu of menu bar 164.

From within the Phonebook window 163, the user can access a profile for any entry by clicking the "open profile' button 167. Initially, the profile window 169 opens with the "Notes" tab 171 open (Figure 22d), thereby presenting the user with a list of notes (including sound files) relating to that person. However, by clicking on the appropriate tab the user can also open the Work tab (Figure 23a), Home tab (Figure 23b), Phone tab (Figure 23c), Personal tab (Figure 23d) or Shortcuts tab (Figure 23e).

The directory component 95 uses the smart data access manager 121 to add, delete, read and modify data accessible from the Phonebook (including the profile).

H. Retrieving a Message The user can retrieve any new voicernail message from the main window 57, which provides an indication of the presence of waiting voicemail by the flashing icon 75 (Figure 24a) and a tool tip indicating the number of messages when the mouse pointer 10 passes over the icon 75 (Figure 24b). A right click on the mouse pointer 10 when positioned over the icon 75 opens a shortcut menu 172 for opening the Call Log (Figure 24c) to play the messages. To display the Call Log (as well as the Redial list, the Calls Missed list or the Calls Answered list), the main window component 83 requests the required information from the smart data access manager 12 1. Call log window 173 opens over the main window 57 and within a Voicemail subdirectory of the Calls Received directory displays the stored voicemail messages (Figure 24d).

Double clicking on the message icon 175 opens a recorder window 177 for is automatically playing the voicemail message. Audio recording and playback requests from the user interface are sent to the smart data access manager 121 which returns an audio file ID. Requests to pause, stop, play, rewind, fast forward, etc. the media stream are sent to the media message control manager 133 using the audiofile ID. 1. Customized Diallers According to another aspect of the invention,

customizable diallers are provided via the software application 17 for allowing the user to create multiple unique dialling sequences which can be implemented during a single telephone call.

This is particularly useful for navigating automated answering and information systems such as voice mail, telephone help linm etc.

W-ath reference to Figures 25a through 25d, various window displays are provided showing operation of the diallers feat= according to the first embodiment.

In Figure 25a, the dialler feature is shown being accessed via the Tools menu 74 of main window 57. As shown in Figure 25b, the dialler window 179 comprises a series of user defined categories or sections 181 of telephone numbers, office extensions or access codes, etc. By clicking on any section 18 1, the section may be opened or closed, while a right click on the mouse opens a menu for editing, opening/closing, etc. Figure 25c shows a particular section 181 (i.e. 4'Citizen Info Line") in the open state. As indicated above, a double click on the name of the section closes it again. In the open state focus is initially on the first of a plurality of user buttons 183. By clicking on the focussed button or pressing the Enter key on keyboard 12, the number associated with the button is dialled and focus shifts to the next button. Each dialler button 183 can start a new ca14 continue a call in progress, or hang up. Standard modem dialler modifiers of the modem 23 are used to insert pauses, wait for dial tone, hookflash, etc., in a well known manner. In this way, a user is able to navigate through a complex series of dialling sequences without being required to memorize the sequence or wait for on-line instructions. As shown in Figure 25d, any button can be edited by effecting a right mouse click when the cursor is over the desired button 183. Likewise, a category or section 181 can also be renamed, deleted or added.

is With reference to the alternative embodiment of Figures 5a though Sc above, the receptionist icon 73 was disclosed as providing access to a plurality of call features such as call screening, call blocking, greetings and personal messages. Upon clicking the receptionist icon 73, a "Personal Assistant" window 185 is displayed as shown in Figures 26a though 26d. The Personal Assistant window 185 includes a plurality of tabs identified as Call Screening (Figure 26a), Call Blocking (Figure 26b), Greetings (Figure 26c) and Personal Messages (Figure 26d). The functionality of each of these features is described within the window tabs of Figures 26a though 26d.
