Abstract

A method and apparatus for allowing a communication from a calling party (120) to a called party (130) to be monitored by a monitoring party (140) and/or recorded (180, 190). Upon receipt of a communication, the service node (180) of the system reads identification information associated with the communication and establishes a bridge for the communication between the calling party (120) and the called party (130), and establishes a bridge from the communication to a monitoring party (140) and/or to a recorder ( 180, 190) in accordance with the identification information. In response to receiving an indication from the monitoring party (140) to tear down the bridge, the system tears down the bridge. However, the communication remains connected between the calling (120) and called (130) parties. Neither the calling party (120) nor the called party (130) are aware of the monitoring or of the recording of the communication or of the discontinuation of the monitoring.

In an intelligent switched telephone network, a method for allowing a communication in said intelligent switched telephone network from a calling party to a called party to be monitored by a monitoring party through said intelligent switched telephone network, regardless of the respective locations of said calling party, said called party or said monitoring party, comprising the steps of:

receiving said communication in said intelligent switched telephone network;

reading identification information associated with said communication for a calling line number or a called party number;

searching for a matching entry to said calling line number or said called party number in a monitoring list maintained by said intelligent switched telephone network, said searching being conducted to determine whether communications to or from said calling line number or said called party number are to be monitored;

routing said communication through said intelligent switched telephone network from said calling party to said called party;

only in response to finding said matching entry,

(a) advising said monitoring party of said communication;

(b) receiving disposition information regarding said communication, said disposition information compromising an indication to monitor said communication; and

(c) establishing a bridge from said communication to said monitoring party, said bridge allowing said monitoring party to monitor said communication through said intelligent switched telephone network regardless of the respective locations of said calling party, said called party or said monitoring party.

6. The method of claim 5, after said step of advising said monitoring party, further comprising the step of requesting said disposition information from said monitoring party.

7. In an intelligent switched telephone network, a method for allowing a communication in said intelligent switched telephone network from a calling party to a called party to be monitored by a monitoring party through said intelligent switched telephone network, regardless of the respective locations of said calling party, said called party or said monitoring party, comprising the steps of:

receiving said communication in said intelligent switched telephone network;

reading identification information associated with said communication for a calling line number or a called party number;

searching for a matching entry to said calling line number or said called party number in a monitoring list maintained by said intelligent switched telephone network, said searching being conducted to determine whether communications to or from said calling line number or said called party number are to be monitored;

routing said communication through said intelligent switched telephone network from said calling party to said called party;

only in response to finding said matching entry, establishing a bridge from said communication to said monitoring party, said bridge allowing said monitoring party to monitor said communication through said intelligent switched telephone network regardless of the respective locations of said calling party, said called party or said monitoring party;

monitoring for an indication from said monitoring party to tear down said bridge; and

responding to said indication by tearing down said bridge.

10. An apparatus in an intelligent switched telephone network for connecting a communication in said intelligent switched telephone network from a calling party to a called party and allowing said communication to be monitored by a monitoring party through said intelligent switched telephone network, regardless of the respective locations of said calling party, said called party or said monitoring party, comprising:

means for receiving said communication in said intelligent switched telephone network;

means for reading identification information associated with said communication for a calling line number or a called party number;
