Cisco Cisco Computer Telephony Integration Option 8.5 Developer's Guide

If one chooses to write a program not using ActiveX controls, a Session object can be created and used 
directly (see CTI Toolkit AgentDesktop at the Win32 CIL samples).

However, in the case of an application built with the ActiveX controls, all ActiveX controls must use the 
same session object. The ActiveX controls accomplish this by retrieving a pointer to the same session 
object via the SessionResolver. The program hosting the ActiveX can obtain the Same session object by 
using the SessionResolver.GetSession method to retrieve a session named “”.

The following sample VB .NET code will retrieve the common session and just listen for a 
CallEstablishedEvent occurring in that session. If a CallEstablishedEvent occurs, it will retrieve 
CallVariable 1 and put it in the Windows Clipboard (from where it can be retrieved via CTRL-v or be 
used by other applications).

This code uses the COM CIL Interfaces and therefore, needs the following references: 
Cisco.CTIOSCLIENTLib, Cisco.CTIOSARGUMENTSLib, Cisco.CTIOSSESSIONRESOLVERLib. 
The references are shown in 

 (in Visual Basic .NET, select Project-> Add Reference...).

Dim WithEvents m_session As Cisco.CTIOSCLIENTLib.Session

' the sessionresolver is needed to retrieve the session pointer
