The purpose of this Recommendation is to define the generic multimedia conference service and to describe their general features, regardless of the network environment in which these services are provided. These services allow conversational communication between several users in two or more locations.The generic multimedia conference service is one of the generic service types identified in Recommendation F.700, and its description follows the methodology described therein. The user requirements for the various applications supported by the service are translated into generic service specifications, independent of the constraints of specific implementations. Thus this Recommendation sets out the requirements that will satisfy the users’ needs and allow proper intercommunication on an international basis of services offered by different providers and of equipment from different manufacturers.
