  • (a) at a service control point (SCP) of the communications system, detecting a Termination Attempt query from a terminating switch processing a received call from a calling party at a calling communication station to a called party at a called communication station;

    (b) in response to the Termination Attempt query, determining at the SCP if standard caller identification information for the calling communication station can be provided to the called communication station;

    (c) if standard caller identification information cannot be provided, communicating a Forward Call message to a service node, the Forward Call message including an identifier for the called communication station and a presentation indicator and (c1) at the service node, in response to the Forward Call message, transmitting a request for spoken caller identification information to the calling communication station, (c2) at the service node, storing the spoken caller identification information when provided, (c3) at the service node, playing the spoken caller identification information to the called party, and (c4) completing the received call only if the called party accepts the call; and

    (d) if standard caller identification information can be provided, (d1) obtaining the standard caller identification information, (d2) comparing the standard caller identification information to a stored intercept list for the called communication station, and (d3) communicating a Termination Attempt response message from the SCP to the terminating switch to complete the received call to the called party only if the standard caller identification information does not match an entry on the intercept list;

    (e) if the standard caller identification was provided and the call was completed, detecting signaling from the called communication station indicating the standard caller identification for the calling communication station should be added to the intercept list for the called communication station; and

    (f) if the signaling is detected, adding the standard caller identification for the calling communication station to the intercept list for the called communication station.
