This supplementary service provides a user with the ability to arrange for a call between more than two participants with all participants accessing a conference bridge. The meet-me conference supplementary service is activated for a specified period booked in advance by the served user.
In due time, each participant in the conference has to dial a special number which has been attached to the booked conference, in order to access the conference bridge.
All indications are sent in-band and/or out-band.
