ABSTRACT:
A caller places a telephone call and enters an access code when calling a subscriber. The caller's access code signal is generated by the caller when the caller inputs his or her access code. The call is transmitted over the Public Switched Telephone Network to a subscriber's telephone number. A Call Router Server capable of receiving the caller's telephone call and the caller's access code signal is provided. The Call Router Server detects the caller's access code signal and then directing the caller's telephone call to the subscriber to be completed in a particular manner based upon the caller's access code. An Access Code Server which is Web server is provided that allows a subscriber to input the manner in which incoming telephone calls will be received and completed based upon the access code signal that is received by the Call Router Server. This information is stored on a Database Server, which instructs the Call Router Server on the proper routing pattern of the incoming telephone call.
