ABSTRACT:
An advanced call monitoring feature which adds an active voice path only between the called party, e.g. a victim, and the monitoring party so remote location of the called party and the monitoring personnel. The active voice path allows monitoring personnel to give instructions or encouragement the called party during lulls in the conversation with the calling party, thus the law enforcement personnel can be actively engaged in the call between the calling party and the called party, even though the monitoring station may be many miles away. This new feature functionality enhances the capabilities and utility of CALEA monitoring.
