A method for providing a remote PBX service by a customer's phone service provider. More than one telephone number is assigned top one customer's telephone communication link. The one customer's telephone communication link is in communication with at least one telephone. A connect signal is received by the customer's phone service provider. The connect signal includes one of the telephone numbers assigned top the one customer's telephone communication link. A called telephone code is generated. The called telephone code is indicative of the one of the telephone numbers included in the connect signal. The called telephone code is sent to the customer's telephone communication link whereby a user of the customer's telephone communication link is capable of knowing which of the more than one telephone numbers assigned to the one customer's telephone communication link was called prior to answering the at least one telephone connected to the customer's telephone communication link. Thus, the customer's phone service provider provides the remote PBX service for the customer without the necessity of a local PBX.
