Silent intrusion
Silent intrusion is a variant of the Intrusion function and is used mainly in call centres.
Another user can intrude on your active call and listen in to your conversation without
you and your call party noticing. Unlike Intrusion you will receive neither a visual nor
an acoustic signal.
This means you cannot reject Silent intrusion. The third user's microphone remains
switched off. He can however intrude on the call at any time by enabling his micro-
phone or pressing the Intrusion function key.
Your system administrator can allocate this function to a configurable key.
