Telephone conferencing systems
First Claim
1. A telephone conferencing system comprising a voice services equipment having a processing means and storage means for storing different identifying codes indicative of different desired participants to a telephone conference, wherein the processing means is operable(i) to request the identifying codes of the desired other participants from the initiator of the conference, and forward the identifying codes to the storage means, (ii) to initiate telephone calls to the desired participants notifying them of the conference and requesting them to call back, and (iii) to receive the returned calls, compare the identifying codes associated with the returned calls with those stored in the storage means, and enable connection to the conference only if particular identifying codes associated with the returned calls match those stored in the storage means.

Abstract
A telephone conferencing system includes a voice services equipment (VSE) allowing a number of telephone calls to be connected together to form a conferencing function. The initiator of the telephone conference calls in on an incoming line and is asked by the VSE to give the telephone numbers of the desired other participants to the conference. These numbers are then stored in a participant number store and the system dials out to these telephone numbers with an invitation to join the conference by ringing a certain number. When the participants call back on the incoming/outgoing lines, their identity is checked, preferably automatically by means of calling line identity signals, with the numbers in the store, and only in the event of a match is each participant allowed to join the conference. For additional security, the participants may also need to enter a specific PIN, which may have been read out by the stem during the invitation to join the conference.
