Abstract
A telecommunication system has capabilities for managing conference telephone calls. Cellular telephones may be registered to the system and may be used as contact devices in setting up conference telephone calls. When a cellular telephone is participating in a conference telephone call and drops out because, e.g., of lost signal, the system may automatically initiate a call back to re-connect the cellular telephone to the conference telephone call.
