With NICE there is a few ways to do this. There is the Agent ROD, like the Witness. There is also a few ways of recording these types of calls, but it depends on what type of logger you have.
If you have a Digital or Analog recorder, you can setup a phone to auto answer, and put a speed dial/confrence on the phones. This would call the recorded station and record it. You can also, if it is a QA system, do he same thing, but make a schedule to record every call to the MCT extension.
I have done all of these in the past, and they all work.
Let me know if I can help anyway else.
