After the filter is set, the client application needs to invoke the EnableSkillGroupStatistics(...) method 
for each skill group that it is expecting to receive statistics. To stop receiving statistics for a given skill 
group, the application must invoke the DisableSkillGroupStatistics method.

'register to receive skill group statistics

sFilterExpression=”FilterTarget=SkillGroupStats"

'call SetMessageFilter

m_session.SetMessageFilter sFilterExpression

'Enable statistics for skills 78,89 and 90 in peripheral 5004

Private Sub m_Session_OnMonitorModeEstablished(ByVal pArguments As Arguments)

Dim m_Args = new  Arguments

   'For Skill 78

    m_Args.AddItem "SkillGroupNumber",78

    m_Args.AddItem "PeripheralID",5004

    m_session.EnableSkillGroupStatistics m_Args

   'For Skill 89

    m_Args.Clear

    m_Args.AddItem "SkillGroupNumber",89

    m_Args.AddItem "PeripheralID",5004

    m_session.EnableSkillGroupStatistics m_Args

    'For Skill 90

    m_Args.Clear

    m_Args.AddItem "SkillGroupNumber",90

    m_Args.AddItem "PeripheralID",5004

    m_session.EnableSkillGroupStatistics m_Args

   'Don't need arguments any more

   Set m_Arg = Nothing

End Sub

Private Sub MyObjectClass_OnCleanupApplication()

    Dim m_Args = new  Arguments

   'For Skill 78

    m_Args.AddItem "SkillGroupNumber",78

    m_Args.AddItem "PeripheralID",5004

    m_session.DisableSkillGroupStatistics m_Args

   'For Skill 89

    m_Args.Clear

    m_Args.AddItem "SkillGroupNumber",89

    m_Args.AddItem "PeripheralID",5004

End Sub

If a monitor mode application does not wish to receive events for silent monitor calls, it can include the 
"HideSilentMonitorCalls" keyword in the filter given to CtiOsSession.SetMessageFilter() to tell CTI OS 
Server to hide events for silent monitor calls. Please see All Calls Sample.NET for an example of the use 
of this filter.
