Abstract
The present invention, relating to the field of communications, discloses a method, device and system for call establishment, wherein the method includes: obtaining the pre-configured binding relationship between conference rooms and terminals; setting the correspondences between terminals of a calling conference room and terminals of a called conference room according to said binding relationship; and establishing media communication with the terminals provided with the correspondences. Embodiments of the present invention also provide a call establishment device and a call establishment system. Embodiments of the present invention overcome various limits and defects due to the fact that calls between other corresponding terminals can only be established via a particular terminal in each conference room in the prior art, and enable a code stream to be transmitted in the shortest path, thereby greatly reducing the path delay and improving the video conference system scalability.
