ABSTRACT:
A system and method delivers an audible tone to an unidentified caller who places a call to a subscriber to a privacy screening service with special information tones (SITs). The service is initiated when an unidentified caller places a telephone call to a subscriber. After the caller enters the telephone number of the subscriber, the service places a query to an SCP. The SCP determines the action to be taken for a call to a subscriber to privacy screening with SITs. If the called party is a subscriber to privacy screening with SITs, a SIT is generated, a privacy screening message is played and the call is handled as in known privacy screening services.
