ABSTRACT:
A system facilitates use of a corporate dialing plan by authorized remote callers. The system includes a receiving element, a sending element, a detecting element, and an establishing element. The receiving element receives a telephone call signal and a telephone number from a remote caller indicating a desire to use the corporate dialing plan for placing a telephone call to a called party using the telephone number. The sending element sends a telephone calling signal to the called party at the telephone number using the corporate dialing plan. The detecting element detects an answer signal from the called party in response to the sending element sending the telephone calling signal. The establishing element establishes a connection between the remote caller and the called party when the detecting element detects the answer signal.
