摘要: The present invention relates to a method, system and gateway device for ena-bling interworking between an IP-based network (30) circuit-switched net-work (10). A first address information (TEL URI) of connection end located in the is routed trigger message from said control function (20). First second call legs are estab-lished parallel towards based on infor-mation, obtained message. single two ends then established by con-necting legs. Thereby, signaling functionality can be used add capability subscribers CS domain invited into conferences or calls with domain, e.g. IMS domain.
