  • the first service package application re-directs a telephone call from a caller to a subscriber'"'"'s telephone number to the service node;

    the second service package application at the service node sends a data request comprising the subscriber'"'"'s telephone number to the first service package application at the service control point;

    the first service package application responds to the data request by retrieving a bypass code corresponding to the subscriber'"'"'s telephone number, and sending that bypass code to the second service package application;

    the first service package application returns a response with a lead number for the service node as the charge number, and the call is routed to the subscriber'"'"'s telephone number.
