Abstract
Abstract A voice services equipment ÄVSEÜ (10) allows a number of incoming telephone calls to be connected together to provide a conferencing function. The telephone calls making up the conference are recorded by a disc store (26) of the VSE (10), and each caller speaking is identified by means of calling line identity (CLI) or the caller's PIN code. If a complaint is made after the conference, an operator at a review station (16) can review the conference and determine which caller caused offence. That caller can be added to a black list held on a database (14), so that further calls from that caller will not be allowed access. <IMAGE>
