Methods of processing incoming telephone calls include receiving an incoming telephone call from a caller, identifying the caller associated with the incoming telephone call, and processing the incoming call in response to a call handling rule generated in response to a menu selection made in a previous incoming call from the caller. Processing the incoming call in response to the generated call handling rule may include playing an interactive voice response menu to the incoming caller. The interactive voice response menu may include at least one menu option included in the interactive voice response menu in response to the call handling rule. Corresponding call handling units and computer program products are also provided.
