Abstract
The call number of a subscriber to be monitored is flagged in the service control point SCP with an indicator of one or more subscribers that are authorized to eavesdrop. When a communications link is set up, an identifier for the monitoring measure is transmitted to the exchange SSP, and a conference loop between the subscriber to be monitored, a calling or called second communications subscriber, and a third subscriber which is authorized to monitor is set up as soon as the identifier is known at the SSP.
