Building a custom CTI application in Visual Basic 6.0 (or adding CTI functionality to your existing 
Visual Basic application) is very simple, but requires basic knowledge of referencing and using COM 
components in Visual Basic. All of the CIL components for COM are distributed as COM Dynamic Link 
Libraries (COM DLL). 

In order to be accessible to COM containers, including Visual Basic 6.0, COM components must be 
registered with Windows. The components that you will require for programming in Visual Basic 6.0 are:

CTI OS Client library (CTIOSClient.dll). This is the main CIL library for COM. The objects 

available in this library are described  fully in the chapters that follow, “Session Object,” “Agent 
Object,” “Call Object,” and “SkillGroup Object.”

CTI OS Arguments Library (arguments.dll). The Arguments helper class is used extensively in 

CTI OS, and is described fully in the chapter “Helper Classes.”

CTI OS Session Resolver (ctiossessionresolver.dll). The Session Resolver is used to share a single 

CTI OS Session across multiple compilation unites (e.g .DLL files). It is only required in 
applications that use ActiveX controls or mix ActiveX controls with custom code.

To make use of these objects in your CTI application, Visual Basic 6.0 uses the concept of referencing 
COM components. To add or remove references within a Visual Basic application, go to the Project / 
References menu.
