A method and system for responding to a trigger condition detected during the handling of a call connection in an intelligent network (IN). Upon receipt of an IN trigger, a service interaction manager in a service control point queries a home location register for a subscriber involved in the call connection requesting subscriber subscription information. The service interaction manager also queries a service library associated with the service control point to determine which of an implicated set of services are currently available in the service library and what the properties of those services are. Depending upon which services are available, which services are in the subscriber's subscription list, and the service priority information received from the home location register and the service library, including the properties data from the service library, the service interaction manager reduces the list of implicated services to an applicable set of services and generates a customized execution sequence for the applicable services. Thereafter, at least one of the applicable services is executed in accordance with the customized execution sequence.
