Purpose

The Bright Pattern Contact Center Desktop Integration API .NET Version Tutorial explains how to use the Bright Pattern Contact Center Desktop Integration API to control agent states and handle calls from .NET-based applications.

For general information about the Agent Desktop functions discussed this tutorial, see corresponding sections of the Bright Pattern Contact Center Agent Guide.

Audience

This tutorial is intended for the IT personnel responsible for the data infrastructure of Bright Pattern Contact Center-based contact centers. Readers of this tutorial are expected to have expertise in web application development as well as a solid understanding of contact center operations.

General Information

The Bright Pattern Contact Center Desktop Integration API .NET Version is encapsulated in the class ADAPI.AgentPlace provided from the assembly ADAPI.dll.

View the complete specification for the .NET version of this API.

Project and Code Setup

1. In the Visual Studio project where you wish to use the Bright Pattern Contact Center Desktop Integration API (.NET Version), add references to the assembly ADAPI.dll and ADUtils.dll.
2. Instantiate an ADAPI.AgentPlace object.
3. Attach event handlers to events generated in ADAPI. This should be done before the agent logs in. For a full list of callback events raised by ADAPI, please consult the API specification.

Threading Model

ADAPI will create its own threads automatically once the AgentPlace object is created. Unless otherwise stated with respect to a particular element, most of the public methods in AgentPlace and other ADAPI objects like Call are asynchronous, and can be invoked safely in any thread. The events in AgentPlace would be raised in the same thread that creates the AgentPlace object.

Agent Login

The AgentPlace object provides the following methods to log in to Agent Desktop for different phone device types:

• For the softphone (isSoftphone=true) or default phone (isSoftphone=false) option,

public void loginOnDefaultPhone(string adHost, string loginId, string domain, string password, bool isSoftphone, bool force = false);

• For the internal phone (isInternal=false) or external phone (isInternal=false) option,

public void loginOnHardPhone(string adHost, string loginId, string domain, string password, string phoneNum, bool isInternal, bool force = false);

• For a nailed connection (option "dial-in and keep line open"),

public void loginOnVirtualPhone(string adHost, string loginId, string domain, string password, bool force = false);

• For the no phone option,

public void loginNoPhone(string adHost, string loginId, string domain, string password, bool force = false);

After authentication, the following event will be raised to indicate whether the login is successful:

public event LoggedInCallback loggedInCallback;

The following method is used to log out:

public override ResultCode logout()

And the following event will be raised once logout is completed:

public event LoggedOutCallback loggedOutCallback;

Agent State

Whenever the agent state changes, the following event will be emitted:

public event StateChangedCallback stateChangedCallback;

The UserState object from the callback provides information about the current agent state and the next agent state.

The following methods are used to set the agent state:

• For the Ready state,

public ResultCode setReady();

• For the Not Ready state with optional indication of the reason (the list of configured Not Ready reasons can be obtained in AgentPlace.notReadyReasons after a successful login),

public ResultCode setNotReady(string reason);

Services

After a successful login, the list of services available to the agent can be obtained from the following property:

public SortedDictionary<string, Service> services;

Making a call

The following method is used to make a call:

public ResultCode makeCall(string dnis, Service service, out ADAPI.Item outItem);

The dnis parameter should not contain any non-numeric characters such as “:”, “+”, or “-”.

The output parameter outItem corresponds to the new ACL item generated for the call.

The following event will be raised when the call is dialed:

public event CallDialingCallback callDialingCallback;

When the other party answers the call and the call is connected, the following event will be raised:

public event CallConnectedCallback callConnectedCallback;

Transfers

The following method in Call is used to transfer a primary call to a consultation party (assuming that there is an active consult call):

public ResultCode consultTransfer(Call consultCall)

The following method in Call is used to make a single-step transfer:

public ResultCode sstepTransfer(string dest)

Conference

The following code snippet shows how to merge calls into a conference.

• For an conference via consultation, it assumes existence of a held primary call and an active consult call. Execution of the code snippet would be triggered by an explicit user action (e.g., pressing of a Merge button).
• For a single-step conference, it assumes existence of an active primary call and another call attempt initiated by the logged-in user. Execution of the code snippet would be triggered by connection of the second call.

To remove a participant from a conference, the removeParty method from Call should be used as follows:

To leave a conference (remove oneself from a conference), use the drop method from Call:

public void drop();

To end a conference, use the endConference method from Call:

public void endConference();

Receiving a call

When a call is made to an agent directly or offered to an agent via an ACD queue, the following events would be raised (in the specified order):

public event ItemArrivedCallback itemArrivedCallback;

public event CallOfferedCallback callOfferedCallback;

Your application can use itemArrivedCallback to create a new item in its active communications list (ACL), while callOfferedCallback, which offers more information about the call (e.g. remote name and number), should be used to update the application about the call. The itemId property in the Call object can be used to find the ACL item by the id property in the Item object.

When the user answers and the call is connected, the following event will be raised:

public event CallConnectedCallback callConnectedCallback;

Call States

The Call object has a set of methods to control call states.

In order to reflect changes in call states to the user, the application should subscribe to the following events:

public event CallConnectedCallback callConnectedCallback;

public event CallDataChangedCallback callDataChangedCallback;

public event CallMutedCallback callMutedCallback;

public event CallUnmutedCallback callUnmutedCallback;

public event CallLocalHeldCallback callLocalHeldCallback;

public event CallLocalResumedCallback callLocalResumedCallback;

public event CallRemoteHeldCallback callRemoteHeldCallback;

public event CallRemoteResumedCallback callRemoteResumedCallback;

public event CallDisconnectedCallback callDisconnectedCallback;

The following properties of the Call object can be used to check the current status of call recording:

public bool isRecording - specifies it the call is being recorded

public bool isRecordingMuted - specifies if the call is being recorded with actual voice replaced by silence (muted recording)

The following Call property specifies the URL postfix which can be used to download the recording.

public string recordingPlaybackUrl

The full URL should be composed by joining the web server address with this postfix.

Assuming that the agent handles one interaction at a time, event callDisconnectedCallback will be normally followed by the stateChangedCallback event. Depending on the contact center configuration, this event may indicate that the agent is in the Ready, Not Ready, or After-call Work state.

Wrapping Up After-call Work

Depending on the service configuration, agent state may be changed to After-call Work after the call is disconnected.

For manual completion of interaction while in After-call Work, use this method for the Item object:

public void complete();

The following event will be raised when the interaction is completed:

public event ItemCompletedCallback itemCompletedCallback;

Note that the same event will be raised if the interaction is finished automatically (by timeout).

Entering Dispositions and Notes

The following code snippet shows how to obtain a list of dispositions for an interaction filtered according to the disposition type:

The method below is used for:

• entering a disposition and notes for a processed call
• rescheduling a call attempt
• indicating whether the voice recording of this call contains a voice signature

public ResultCode disposition((string dispositionId, string notes, DateTime reschFrom, DateTime reschTo, string reschPhone, string reschTZ, bool bVoiceSignature);

This method can be used both while the call is in progress and after it is disconnected while the user is in the After-call Work state.

Directory

There are two types of directory items in the AgentPlace object that are available immediately after the agent logs in: users grouped in teams, and static entries grouped in categories (folders).

The list of Team objects can be accessed via:

public SortedDictionary<string, Team> teams;

This list corresponds to the teams in the Contact Center Administrator application. The User list associated with a Team is loaded on demand by the following method in Team:

public void requestMembers(bool includeLoggedOut);

When the User list is available, the following event from the AgentPlace is raised:

public event TeamMembersReceivedCallback teamMembersReceivedCallback;

If your application needs to receive notifications about changes in attributes of a team member, the following method in Team should be invoked:

public void subscribe();

When any change in attributes of a team member occurs in that team, the following method is raised:

public event UserInfoUpdatedCallback userInfoUpdatedCallback;

Note that only one team subscription is allowed at a time (a new subscription will cancel the previous team subscription).

The list of DirectoryCategory objects can be accessed via:

public SortedDictionary<string, DirectoryCategory> directoryCategories;

This list corresponds to the list of folders of static entries in the Contact Center Administrator application. The DirectoryItem list associated with DirectoryCategory is loaded on demand by the following method in DirectoryCategory:

public void requestItems();

When the DirectoryItem objects are available, the following event from AgentPlace is raised:

public event DirectoryItemsReceivedCallback directoryItemsReceivedCallback;

Recent Interactions

The list of recent interactions for the logged user is available in the following property in AgentPlace after agent login:

public SortedDictionary<string, Recent> recents;

The following code snippet shows how to sort the recent interactions according to the timestamp of the interactions:

Favorites

The following method from AgentPlace is used to add a contact to the favorites list of the logged user:

public Favorite addToFavorites(string name, string number);

The list of favorites is available in the following property in AgentPlace after agent login:

public SortedDictionary<string, Favorite> favorites;

The following method from AgentPlace is used to remove a contact from the favorites list:

public ResultCode removeFromFavorites(string number);

Notifications

The following events in AgentPlace are raised when the corresponding conditions are detected in the logged user’s Agent Desktop environment. Your application may use these events to alert the users.

When the user's softphone status changes:

public event SoftphoneStatusCallback softphoneStatusCallback;

When the input or output audio device is changes:

public event AudioDeviceChangedCallback audioDeviceChangedCallback;

When the user's phone capabilities change:

public event PhoneCapabilitiesChangedCallback phoneCapabilitiesChangedCallback;

When the audio quality problem is detected for the current call:

public event CallAudioQualityAlertCallback callAudioQualityAlertCallback;

When an error occurs:

public event ErrorCallback errorCallback;
