An apparatus, method and system are provided for roamer originated automatic telecommunication conferencing and broadcasting. The system embodiment includes a first switch for reception of a first incoming call leg from a roaming mobile unit or from another telecommunication device outside its assigned serving area. The first incoming call leg preferably designates a multiple leg service, such as a telecommunication conference, and also designates a subscriber group. Each particular subscriber group is predefined, and consists of a list of directory numbers to be included within the conference or broadcast session. In the various embodiments, the first switch communicates with a second switch or a database, and obtains a routing directory number to reroute the first incoming call leg, to form a second incoming call leg to the second switch. The system embodiment also includes a conference bridge coupled to the second switch, in which the conference bridge includes instructions to receive the second incoming call leg routed from the second switch, to determine the plurality of directory numbers associated with the subscriber group, and to return to the second switch a plurality of intermediate incoming call legs corresponding to the plurality of directory numbers for routing by the second switch to form a plurality of outgoing call legs. The conference bridge also includes further instructions to monitor answering of the plurality of outgoing call legs, and to connect an outgoing call leg indicating joinder, of the plurality of outgoing call legs, to the conference bridge for a multiple leg telecommunication session, such as a conference or broadcast session.
