Lead lists used by volunteer callers are furnished by BAT Task Force agencies. These are the names of potential victims obtained in the course of fraud investigations. Because the warning calls to these persons are intended to reverse the action of the Boiler-room operators, this kind of activity is called a Reverse Boiler-room Operation (RBO).

Persons whose names are found on Boiler-room lead lists used by the TVCC come from every part of the country; thus, the TVCC has a national-level function, serving potential victims around the United States. For this reason, expenses incurred by AT&TWS for telephones used at the TVCC is significant.

In countless instances, persons who have lost five- and six-figure amounts have been counseled by TVCC callers. Victims have told the TVCC fraud fighters that they had "learned their lessons" and would not send more money to suspicious telemarketers because of inherent risks. It is believed that fraud fighters have made a dent in the $40 billion dollars of telemarketing fraud perpetrated yearly in the United States.

To better focus on the TVCC's primary mission of warning identified potential victims of telemarketing fraud, the TVCC handles only outgoing telephone calls, and does not take incoming telephone calls.
