CONNECTION CONTROLLER FOR MANAGING MEDIA PATHS BETWEEN TERMINAL DEVICES RESIDING IN DIFFERENT NETWORK DOMAINS

摘要

A terminal proxy for a PBX. The terminal proxy manages the flow of media signals originating or arriving at a terminal device residing in a packet switched network. The terminal proxy has a first interface for communicating with the terminal device using a terminal device protocol, and a second interface for communicating with a media path server using a media path server protocol and an interoperation functional unit. The interoperation functional unit effects manipulations on signaling information received by said first interface and by said second interface, to allow the terminal device and the media path server to interoperate for effecting management of the flow of media signals originating or arriving at the terminal device. The invention also provides a PBX that has a call manager and a connection controller. The connection controller is responsible for the management of media paths during call sessions between terminal devices set-up by the call manager. The call manager sends signaling information to the connection controller that is independent of the connection type of the terminal devices.
