Abstract (en)
[origin: WO2006035050A1] The invention relates to a method for establishing a multimedia connection between at least one calling user (RT) and at least one called user (SIP) via packet-oriented computer networks. The inventive method is characterized in that the users independently recognize contradictory requests (BICC APM, BICC APM1; UPDATE offer, UPDATE offer 1) of the calling user and the called user to each other and then send a request for delaying execution of the respective task (BICC APM3, 500(retry after)) to the respective call partner if contradictory requests (BICC APM, BICC APM1; UPDATE offer, UPDATE offer 1) occur.
