Abstract: There is described a transmission of user data from a source communications device provided with a first encoder for encoding users data to a target communications device provided with a first decoder for decoding said user data via a communication network which is provided with several converting devices comprising additional encoders and additional decoders for carrying out a verification of the converting devices. Via the verification it is determined, whether the first encoder is compatible with the decoder of a given converting device and, whether the first decoder is compatible with the encoder of said converting device. One of the converting devices for which the compatibility is ascertained by the verification is selected for transmitting user data.

Abstract: In one aspect, a method for establishing communication in a packet-oriented communications network between a calling (EG1) and a called terminal is provided. In the method, before a call-accepted signal by the called terminal, triggered by a message within the framework of call set-up signaling, a direct, first payload connection is established and maintained between the calling and the called terminal. As a direct result of the call-accepted signal of the called terminal communication is triggered between the calling and called terminal by means of the established first payload connection.

Abstract: Transmitting communication data for a connection between at least one calling first terminal and at least one called second terminal in an at least partly packet-oriented network comprising a plurality of node units, a primary connection being established via the packet-oriented network is provided. User data is detected and evaluated in the first node unit that is designated as a terminal node when the primary connection is established. Parameters of the node unit that are adjustable for converting and/or transmitting the user data are adapted to the evaluated user data. The parameters are transmitted to a second node unit that is designated as a terminal node, whereupon a direct media coupling connection is established between node units which have been designated as terminal nodes along the primary connection, the direct media coupling connection being established with parameters that are adapted to the evaluated user data.

Abstract: A method for setting up a useful data connection between a first terminal device connected to a first connection controller and a second terminal device connected to a second connection controller is provided. In this case connection setup signaling is initiated by the first terminal device via possibly intermediate connection controllers to the second connection controller, in the course of which first useful data parameters specific to the first terminal device are transmitted to one of the connection controllers. As a result of the connection setup signaling, a connection setup message is transmitted without the first useful data parameters from the second connection controller to the second terminal device. Upon connection acceptance, a connection acceptance message is transmitted by the second terminal device from the second terminal device to one of the connection controllers, and subsequent thereto the first useful data parameters are transmitted to the second terminal device.
