A server allows a worldwide telephone number associated with a local telephone to be shared by one or more remote telephones. A call placed to the worldwide telephone number rings at the local telephone and at least one of the remote telephones. The server stores a set of telephone numbers to be associated with a worldwide telephone number serviced by the switch to which the local telephone is connected. The server receives notification of a telephone call from a calling telephone to the worldwide telephone number The server retrieves the set of telephone numbers associated with that worldwide telephone number, and places calls to telephone numbers in the set through the switch. The server then causes a connection to be made between the local telephone or the remote telephone, depending on which telephone goes off hook first, to the calling telephone. In one embodiment of the present invention, the server causes the connection to be made by causing the switch to make a conference call connection between the calling telephone and the remote telephone.
