ABSTRACT:
A communications network having a dial-up conference arrangement is disclosed. The conference host can summon an operator and cause the conference details to be displayed at an operator position. The detailed information presented to the operator permits the operator to identify conferees independently of the directory number that was used to dial-up the conferee. This permits the operator to redial dropped legs, transfer control of the conference and perform other functions with respect to the identified conferee.
