Abstract: A method for providing selectable real-time audio connections between an executing communication unit (1) and a plurality of further communication units (2) in a communication group (3). The executing communication unit (1) establishes a connection to a data network, determines further communication units (2), forms a communication group (3) that comprises the executing communication unit (1) and at least one further communication unit (2), defines an address assignment for an audio channel to the at least one remote communication unit, receives a user input for activation of the real-time audio transmission by selecting an activation element (4), and opens the audio channel.
