Abstract (en)
[origin: WO2005079049A1] The invention concerns a communication set up between subscribers (A, B) by means if an interactive voice response system (IVR). The generation of a recall of the subscriber (A) is controlled by signalling messages serving to warn the subscriber (B) of a call. A direct link TDM, RTP/RTCPA/B in the multimedia network (IN) is set up between the two subscribers (A, B) at latest when the communication is set up. Thus, it is possible to provide intelligent IVR network power characteristic of the PSTN network power in a multimedia packet transmission multimedia network (IN), such that a recall is properly displayed. The direct TDM, RTP/RTCPA/B link further enables the IVR system to be significantly free of load
