In a telephone network, customized advanced intelligent network (AIN) services are provided to standard IN/1 "800" service customers. An IN/1 service switching point (IN/1 SSP) receives a call directed to the standard IN/1 "800" service customer, and generates an "800" query to an "800" services data base. An "800" service control point ("800" SCP) generates an "800" response containing a carrier identification code, and the IN/1 SSP routes the call via a trunk group designated by the carrier identification code. An AIN-equipped service switching point (AIN SSP) then generates an AIN query to an AIN services data base. In response, an AIN-equipped service control point (AIN SCP) executes AIN service records corresponding to the standard IN/1 "800" service customer to generate an AIN response containing call processing instructions. The AIN SSP then uses the call processing instructions to complete the call.
