摘要:
A system and method enables a caller to detect subscribers to a privacy screening service. The caller detection of privacy screening is initiated when a subscriber to the caller detection of privacy screening service places a telephone call to a called party. After the calling party enters the telephone number of the called party, the caller detection of privacy screening service places a query to an SCP. The SCP determines if the called party is a subscriber to privacy screening. If the called party is a subscriber to privacy screening, the call is not completed, and a message is sent from the SCP to the SSP indicating that this is a caller detection of privacy screening call. This information is forwarded from the SSP to a billing system for processing as a caller detection of privacy screening charge. If the called party is not a subscriber to privacy screening, the call is completed and normal charges accrue.
