Abstract: A method and apparatus for communication between an automatic branch exchange and a messaging system using a signaling channel. The signaling channel bearing at least some of the signaling exchanges between the automatic branch exchange and the messaging system. The automatic branch exchange and the messaging system are also interconnected by voice channels so as to implement voice services on the messaging system. The signaling channel is distinct from the voice channels.

Abstract: The invention relates to a method for the management of a telephone automatic branch exchange (11) provided with a management program that makes use of the raw configuration data of a basic configuration enabling its operation. The method comprises a phase of initialization that consists in structuring the configuration into a plurality of objects characterized by parameters and in describing the basic configuration in the form of a raw data base; a phase for the extraction of a configuration diagram that consists in exploring the raw data base so as to prepare a diagram of configuration instructions constituted by a list of configuration instructions; an optional phase for the transfer of the diagram from an external management device to the telephone automatic branch exchange and/or prepare and upload the diagram within the device to store a descriptive condensed image of the current configuration of the telephone automatic branch exchange.
