Abstract
In order to operate a multimedia communications network having at least two endpoints and at least one registration unit, a more simple identification of the media connection for the purpose of bandwidth reservation and service quality assurance in the transport network is achieved in that, after the arrival or authorization of a call, a call status request message is transmitted by the registration unit to the endpoints respectively involved in the call, which call status request message includes a request to the endpoints to report, in a call status acknowledge message, the properties of a media and/or data connection which is set up between the endpoints in connection with the call.
