Conference Calling is an ISDN supplementary service which allows a user to communicate simultaneously with multiple parties, which may also communicate among themselves.This description deals primarily with the establishment and manipulation of the connections used to form a conference call and is therefore expected to be applicable to many types of conference calls (e.g. voice, data, video, multi-media).Although provision is made for specifying the conference type,it is recognized that the control of conferencing functions (especially for those other than speech) is beyond the scope of this Recommendation.This Recommendation describes the operation of the “Add-on” Conference Calling service only.Other forms of Conference Calling (e.g. “Meet-me”) are not described.
