Override 
 
An authorized network station (such as the central attendant position or a HiPath 3000/5000 station with override authorization) can override a call being conducted at a busy station in the network. Users cannot override conference calls in HiPath 3000/5000. The feature is implemented according to QSig specification CI (call intrusion).
The HiPath 3000/5000 systems handle a busy override according to QSig in a network just like an internal busy override. This means that every user who is authorized to override busy calls is authorized to do so throughout the network. The override operation transforms a two-party call into a three-party call.
