ABSTRACT:
All calls terminating to a customer's directory number are intercepted. If caller identification information can be presented, the call is forwarded to a service node for disposition. The service node reconfigures signaling information of the call so that the call is not intercepted, then forwards the call to the subscriber's telephone. When the call is answered, the service node states the name or telephone number of the calling party which has been retrieved from the signaling information. The caller can decide whether to take the call, deny the call, send the call to voice mail or send a sales refusal message or other disposition option.
