Method and system for improving establishing of a multimedia session

摘要

Multimedia communication systems and methods are disclosed. An exemplary system comprises a server adapted to communicate with two or more multimedia endpoints; and a MCU adapted to communicate with the at least one server and the multimedia endpoints, wherein the server contains a module for instructing the multimedia endpoints to call a dial number for the MCU to establish a multimedia conference in response to a requested list of multimedia endpoints received from one of the multimedia endpoints. An exemplary method for establishing a multimedia conference comprises receiving at a server from a first endpoint a requested list of second endpoints desired to participate in the multimedia session; reviewing at the server the status of the second endpoints; and if the status of a particular second endpoint is an available status, instructing at least some of the available second endpoints to call a dial number for a MCU to participate in the multimedia conference. A further exemplary method allows for a determination to be made whether a multipoint or point-to-point conference is required, and allows a user to leave a message for users who unavailable to participate in the conference.
