Methods, computer readable media, and apparatuses for managing calls in an interactive voice response system are presented. According to one or more aspects, a call from a user or customer is received by an interactive voice response system. The interactive voice response system retrieves user information based on user credentials. An interactive voice response program analyzes the user information and determines a first business rule to retrieve. A decision tree application retrieves the first business rule and analyzes the information within the first business rule. The decision tree application may retrieve one or more additional business rules based on a decision from the first business rule. The decision tree application makes a decision based on the information within the business rules and sends the decision to the interactive voice response application. Based on the decision, the interactive voice response application manages the call in the interactive voice response system.
