A "Call Me" conference call system includes a multiport conference unit (MC U) interconnected with the public switched telecommunications network (PSTN), a telecommunications switching system also interconnected with the PSTN, a service control point (SCP) or other intelligent network control component having at least a signaling connection to the switching system, a Call Me conference bridge reservation system interconnected with the SCP and the MCU, and suitable facilities interconnecting these components. When a conference reservation is made, information regardi ng the conference is distributed to the SCP and MCU. A "Called Party Busy" trigger is applied to the conference host's line. To join the conference, the host and participants alike simply call the host's telephone number. The switching system, finding the host's line busy, queries the SCP, which instructs it to redirect the call to the MCU. T he MCU associates the call with a reserved conference by matching the called number with a host's telephone number in reservation records. This advantageously avoids the need for hosts to distribute, and participants to receive a special conference bridge telephone number or access code.
