Abstract
A system and method are disclosed for alerting a person placing a telephone call when a dialed number subscribes to a Caller Identification Service. A long distance party is called direct using standard 1+ calling. The call is routed through a long distance carrier switching network which is coupled to a signaling network. The signaling network routes the caller'"'"'s identification information together with the dialed number to the switches in the switching network. The switching network includes a subscription table for determining whether the dialed number subscribes to the aforesaid service. If the dialed number is a subscriber, the caller'"'"'s identification information and the dialed number are routed from the switching network to a Customer Long Distance Adjunct. The adjunct transmits a message to the caller via the switching network informing the caller that the dialed number is a subscriber. The message may also instruct the caller on the procedure for blocking or unblocking delivery of his identification information. The caller is then provided with the opportunity to direct the adjunct to block or unblock delivery of this information to the dialed number.
