Abstract: The present invention concerns a device for communication networks comprising a connection member and network database. A first subscriber, equipped with a multimedia terminal, makes a connection to a second subscriber, equipped with a number of services connected to various terminals. The first subscriber wants to use several facilities in parallel during the communication. This is recorded in the network database which ensures that the relevant services at the second subscriber are used for the connection . Thereafter the subscribers can communicate with each other over several parallel facilities. In addition, the first subscriber has the ability to request, during the communication, the connection of further facilities which were not connected at the beginning of the communication.
