Purpose

The Bright Pattern Contact Center Simplified Desktop .NET API Specification describes the methods and events of the Simplified Desktop .NET API, which provides access to a number of functions of the Bright Pattern Contact Center Agent Desktop application from .NET-based third-party applications.

For more information about the Agent Desktop application, see the Bright Pattern Contact Center Agent Guide.

General Information

The API supports the following functions:

The API itself does not replace the softphone functionality; the Bright Pattern Contact Center Agent Desktop application with a softphone (or hardphone) must be running on the user’s computer in order for the API to function.

The API communicates with Agent Desktop locally, and therefore, an Agent Desktop session must be started and the softphone plugin (Agent Desktop Helper Application) must be active.

The API uses the identity of the user logged into the Agent Desktop application in the current Windows session.

Event Delivery

Communications with the softphone plugin are handled by the lowest level of the API; all transport is handled by the .NET platform and all transport-related events are delivered on threads maintained by the platform. Note that direct updating of the UI (either Windows Forms, or WPF) is only permitted on the UI thread--in most cases, the main thread of the application. Although different mechanisms exist to convey execution flow from non-UI to UI threads, the API has its own mechanism that allows receiving events emitted by the API classes on the UI thread--event dispatcher classes.

Each API class has a child class named eventDispatcher (referred to as "event dispatcher"). The event dispatcher class intercepts and re-emits all events emitted by its parent class, while guaranteeing that the events will be delivered on the thread on which the API has been created. Event handlers registered with the API’s event dispatcher class created on the UI thread may directly update elements of the application's UI.

All events emitted by all objects follow Microsoft's guideline that asks that all event handlers take two parameters: the object that has emitted the event and another object that encapsulates all arguments of the event. Such an argument object should inherit the System.EventArgs class and provide any additional data or capabilities in the form of additional properties and methods. All events emitted by the event dispatcher objects carry the reference to the original sender object.

API Instantiation and Initialization

First, the client should create an Api object and attach event handlers:

m_api = new DesktopControlAPI.ApiLite();
m_api.eventDispatcher.evtApiUp += this.onApiUp;
m_api.eventDispatcher.evtApiDown += this.onApiDown;
m_api.eventDispatcher.evtCallOffered += this.onCallOffered;
m_api.eventDispatcher.evtCallDialing += this.onCallDialing;
m_api.eventDispatcher.evtCallDisconnected += this.onCallDisconnected;


Note that by default API logging is enabled:

ApiLite(bool _enableLog = true);

To disable logging, set enableLog to false.

m_api = new DesktopCOntrolAPI.ApiLite(false);


Once API is created and event handlers are attached, the client may initialize the API instance:

m_api.InitAPI();


Once API is connected to the softphone and the evtApiUp event is received, the client may dial calls:

m_api.CallDial(“4154556565”);


When application terminates the following method should be called to ensure clean termination of the TCP connection between API and the Agent Desktop:

m_api.ShutdownAPI();

API Methods

InitAPI

InitAPI initializes the API.

This request initializes the TCP connection procedure. Once connection is established, the evtApiUp event is sent to the .NET application.

Syntax

bool InitAPI();


ShutdownAPI

ShutdownAPI terminates the TCP connection between the API and the Agent Desktop.

Syntax

void ShutdownAPI();


CallDial

CallDial initiates a call to the number specified in destination.

Specification of the global interaction identifier (GIID) is optional. This returns request ID.

Syntax

UInt64 CallDial(string destination, string giid);


MuteCallRecording

MuteCallRecording mutes audio recording of the call identified by callId on the given desktop.

The recording will continue, but any voice signal will be replaced with silence.

Syntax

UInt64 MuteCallRecording(string callId);


UnmuteCallRecording

UnmuteCallRecording resumes previously muted audio recording for the call identified by callId on the given desktop.

Syntax

UInt64 UnmuteCallRecording(string callId);


MuteScreenRecordings

MuteScreenRecordings mutes screen recording on the given desktop.

For the period when screen recording is muted, the recording will contain a static snapshot of the desktop at the moment when mute was applied.

This request is processed by the Agent Desktop Helper Application.

Syntax

UInt64 MuteScreenRecordings();


UnmuteScreenRecordings

UnmuteScreenRecordings unmutes previously muted screen recording on the given desktop.

This request is processed by the Agent Desktop Helper Application.

Syntax

UInt64 UnmuteScreenRecordings();

API Events

evtApiUp

evtApiUp is sent when the API is successfully connected (or reconnected) to the softphone.

Note that no information is provided about calls that already may be present on the Agent Desktop.

Syntax

void evtApiUp(System.EventArgs args);


evtApiDown

evtApiDown is sent when the ShutdownAPI method is called or when the API loses connection to the softphone.

In case of connection loss, the API will try to reconnect every 15 seconds; once reconnected, the evtApiUp event is sent.

Syntax

void evtApiDown(System.EventArgs args);


evtCallDialing

evtCallDialing is sent when the softphone starts dialing a call.

Note that this event reports calls both initiated by a prior CallDial method and dialed directly from the Agent Desktop.

For parameters, see the description of auxiliary class DesktopControlAPI.CallArgs.

Syntax

void evtCallDialing(DesktopControlAPI.CallArgs args);


evtCallOffered

evtCallOffered is sent when the softphone receives a new incoming call.

For parameters, see the description of auxiliary class DesktopControlAPI.CallArgs.

Syntax

void evtCallOffered(DesktopControlAPI.CallArgs args);


evtCallDisconnected

evtCallDisconnected is sent when an existing call is released.

For parameters, see the description of auxiliary class DesktopControlAPI.CallArgs.

Syntax

void evtCallDisconnected(DesktopControlAPI.CallArgs args);


onError

onError is sent when an error occurs while executing a method.

For parameters, see the description of auxiliary class DesktopControlAPI.ErrorEventArgs.

Syntax

void onError(DesktopControlAPI. ErrorEventArgs args);


onCallRecordingStarted

onCallRecordingStarted is sent when call recording is started.

For parameters, see the description of auxiliary class DesktopControlAPI.CallArgs.

Syntax

void onCallRecordingStarted(DesktopControlAPI.CallArgs args);


onCallRecordingStopped

onCallRecordingStopped is sent when call recording is stopped.

For parameters, see the description of auxiliary class DesktopControlAPI.CallArgs.

Syntax

void onCallRecordingStopped(DesktopControlAPI.CallArgs args);


onCallRecordingMuted

onCallRecordingMuted is sent when call recording is muted.

For parameters, see the description of auxiliary class DesktopControlAPI.CallArgs.

Syntax

void onCallRecordingMuted(DesktopControlAPI.CallArgs args);


onCallRecordingUnmuted

onCallRecordingUnmuted is sent when call recording is unmuted.

For parameters, see the description of auxiliary class DesktopControlAPI.CallArgs.

Syntax

void onCallRecordingUnmuted(DesktopControlAPI.CallArgs args);


onScreenRecordingStarted

onScreenRecordingStarted is sent when screen recording is started.

For parameters, see the description of auxiliary class DesktopControlAPI.ScreenRecordingArgs.

Syntax

void onScreenRecordingStarted(DesktopControlAPI.ScreenRecordingArgs args);


onScreenRecordingCompleted

onScreenRecordingCompleted is sent when screen recording is stopped.

For parameters, see the description of auxiliary class DesktopControlAPI.ScreenRecordingArgs.

Syntax

void onScreenRecordingCompleted(DesktopControlAPI.ScreenRecordingArgs args);


onScreenRecordingsMuted

onScreenRecordingsMuted is sent when screen recording is muted.

For parameters, see the description of auxiliary class DesktopControlAPI.BaseEventArgs.

Syntax

void onScreenRecordingsMuted(DesktopControlAPI. BaseEventArgs args);


onScreenRecordingsUnmuted

onScreenRecordingsUnmuted is sent when screen recording is unmuted.

For parameters, see the description of auxiliary class DesktopControlAPI.BaseEventArgs.

Syntax

void onScreenRecordingsUnmuted (DesktopControlAPI.BaseEventArgs args);
