description The invention relates to a method fro carrying out a Push-to-Talk communication in a digital and/or analogue telephone network, the device being designed as interface for a semi-duplex communication between a Push-to-Talk server and the analogue or digital telephone network and the analogue or digital network serves as interface with the operating means. The invention is characterised in that the interface uses a communication node or group system as computer and carries out a communication in a transmission channel with automatic directional switching in an analogue or digital telephone network in the direction of an available Push-to-Talk server, the analogue or digital telephone network being designed as an audio and control interface in the direction of the operating means.
