Get the current action after the clicked button

[mndir]

Hello friends,
I want the current action of the clicked button. Example, if a call is on hold during 30s, alert the user.
This is to start a thread in relation to the action.
All help is welcome.
I am new in precise customization of iws

What is your current code-behind? Try to describe clearly, what is not clear for you within the task.

Thank you for answering and forgive my bad English.
In fact I want to alert the user when time hold  is x seconds.
I try to intercept the click of button hold but cannot get the statistics data. I do not have the SDK to statistic.
I have this code
  commandManager.CommandsByName ["InteractionVoiceHoldCall"]. Insert (0,
                CommandActivator new () {CommandType = typeof (BeforeResumeCallCommand)});

But it does not help me much to have the hold time

Why not create a metric for him on IWS and just give levels to it?
