ABSTRACT:
At least one switching instance is provided in a VoIP system in order to set up a useful data link between a calling terminal and a called terminal. A first signaling link is set up between each terminal and the at least one switching instance for interchanging information on the basis of a first protocol, a second signaling link is set up between them for interchanging information on the basis of a standardization second protocol, in which the useful data link is set up on the basis of the information interchanged on the basis of the second protocol. At least the second signaling link is initiated by the calling terminal, with the information which is transmitted via the first signaling link and in parallel via the second signaling link from the terminals being in each case combined.
