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 microphone or pressing the Intrusion function key. Aastra 650c 69 eud-1587/1.0 - R3.0 - 04.2013
