This invention provides for a unified alerting system that alerts the subscriber via one or more devices. The unified alerting system receives alert events from services subscribed to by the subscriber, filters the alert events and alerts the subscriber via one or more devices identified in a subscriber profile. The alert event is filtered by if-then-else statements that contain conditions and actions. Conditions have Boolean values and the actions set various control variables or may be further if-then-else statements. In this way, the subscriber may specify complex conditions that process each alert event to determine whether the subscriber should be alerted via one of the available devices. The subscriber profile specifies possible devices through which the subscriber may be alerted via a schedule corresponding to each of the devices. The profile also includes a priority level for each of the devices when multiple devices are available. The unified alerting device may also perform various conversions such as voice-to-text and text-to-voice so that messages may be sent in an alert regardless of the capabilities of the devices used.
