Add ability to play a goodbye Message in queues after the maximum waiting time and then to end the call. So far this is only possible when you connect to an IVR. The IVR will play the goodbye Message and end the call. The Problem is, that this is not a nice and clean solution, because while you connect from queue to IVR you hear the onhold music. Also sounds like "thankyou_goodbye.wav" or "pleasehold_calling.wav" which you do not want there.
