Cisco Cisco Computer Telephony Integration Option 9.0 Developer's Guide

The StandAlone Com Object is a COM dll that needs to be registered on the client system via the 
Regsvr32 Silentmonitorctl.dll. In addition, ccnsmt.dll and the two standard CTI OS COM dlls 
(CTIOSClient.dll and Arguments.dll) are also required.

The following sample code assumes a VB 6.0 form with 4 buttons (Connect, Disconnect, 
StartMonitoring and StopMonitoring. If the parameters are based on edit fields, the source code below 
is all that is needed to silent monitor via CTI OS. It is important to note, that this control does not require 
supervisor privileges or even any login. The only event handler shown below (OnSessionDisconnected) 
is the one for a timed out Silent Monitor session. Other event handlers.

Dim WithEvents SilentMonitorCtl As SILENTMONITORCTLLib.SilentMonitor

Dim m_Args As New Arguments

Const CIL_OK = 1

Private Sub btnConnect_Click()

    m_Args.clear

   m_Args.AddItem “CtiosA”, “localhost”

   m_Args.AddItem “portA”, “42028”

    Dim nRetVal As Long

    SilentMonitorCtl.Connect m_Args, nRetVal

    If nRetVal <> CIL_OK Then

       MsgBox "Connect returned error " + Str(nRetVal)

    End If

End Sub

Private Sub btnDisconnect_Click()

    Dim nRetVal As Long

    SilentMonitorCtl.Disconnect

End Sub

Private Sub btnStartMonitoring_Click()

     m_Args.clear

     m_Args.AddItem “AgentId”, “1000”
