The IP Office system supports several different methods for call intrusion. The method used affects which parties can hear each other. Intrusion features are supported across a multi-site network.
Intrusion features are controlled by the Can Intrude setting of the user intruding and the Cannot Be Intruded setting of user being intruded on. By default, no users can intrude and all users cannot be intruded.
Intrusion features uses system conference resources during the call. If insufficient conference resource are available, the feature cannot be used.
In the examples below, A has called or is calling IP Office user B. A can be internal or external. User C invokes one of the call intrusion methods targeting user B.

Call Steal Take a connected or alerting call from another user.
If the target has multiple alerting calls, the function steals the longest waiting call.
If the target has a connected call and no altering calls, the function steals the connected call. This is subject to the Can Intrude setting of the Call Steal user and the Cannot Be Intruded setting of the target.
If no target is specified, the function attempts to reclaim the user's last ringing or transferred call if it has not been answered or gone to voicemail.
Stealing a video call changes the call to an audio call.
R11.1 FP2 SP4 and higher: The shortcode for this feature can be used with the user's own extension number. That enables twinned and simultaneous device users to move a connected call from another one of their devices. This usage ignores the user's privacy and intrusion settings.
