  • a first switch receiving caller identification data and signaling system data of the call, the first switch determining if the caller identification data includes valid information and when the caller identification data does not include valid information, the first switch providing the call to a peripheral system;

    if the caller identification data includes valid information, the first switch comparing the caller identification data to the signaling system data to identify the false caller identification if the caller identification data is not consistent with the signaling system data, the first switch providing the call to the peripheral system upon detecting false caller identification, the first switch providing the call to the intended recipient if the caller identification data is consistent with the signaling system data; and

    the peripheral system holding the call and contacting the intended recipient with an automated voice message providing information about the call and giving the intended recipient options of connecting the call, terminating the call, and sending the call to voicemail, wherein the peripheral system comprises a user interface that allows the intended recipient to selectively connect with the call, wherein the peripheral system stores the caller identification data for access by the intended recipient after the call is terminated;

    wherein the first switch modifies the caller identification data when the false caller identification is detected based on the signaling system data, the switch modifying the caller identification data to identify the presence of false caller identification;
