Abstract: A telephony call connection process is provided which assumes that 100% of received calls have spoofed sources or contain otherwise untrustworthy caller-id (CID) information, and requires each caller to provide a prearranged personal identification number “PIN” (or secret code) associated with their caller-id (CID) in order to complete a connection. Additional mechanisms are provided to create and exchange the PIN (or secret code) in an environment in which the caller must first establish the ownership of the caller-id (CID) provided. The process described herein minimizes the risk of false positives and virtually eliminates the need for manual “screening” as is often required of the callee in similar systems. Furthermore, the process described herein is capable of operating entirely on the callee's equipment providing the same level of effectiveness entirely devoid of participation from any other switch or node in the call path or on the network.
