ABSTRACT:
A subscriber associated with a private branch exchange (PBX) terminal without a Direct-Inward-Dialing (DID) line establishes a first call connection with a particular service node via a mobile station. The subscriber then instructs the service node to originate a second call connection from the service node towards the PBX serving said subscriber. The first and second call connections are interfaced to enable the subscriber to communicate with a PBX operator answering the second call connection. The subscriber then instructs the operator to forward the received call to the subscriber's PBX terminal. Thereafter, the subscriber instructs the service node to originate a third call connection towards a particular called party terminal. The established third call connection is interfaced with the second call connection to enable the subscriber to communicate with the called party subscriber terminal via the PBX terminal. The first call connection with the mobile station is terminated. Since no outgoing call connection has been originated by the PBX, no additional PBX associated charges are incurred by the subscriber for the communication.
