If you’ve know a bit about the audio conferencing sector you will virtually absolutely have encountered the term ‘reservationless audio conferencing’ yet what does it mean? According to the Oxford Thesaurus there is no such word as reservationless but it appears to have worked its method right into the lingo of teleconferencing. Reservationless, as the name recommends, simply indicates that you do not have to reserve your area at the audio conference in advance of the telephone call.
