A system and method are provided for reviewing and updating a subscriber's telecommunications services using a graphical user interface via multiple data networks. A data message is received at an intelligent peripheral from the graphical user interface via at least one of the data networks. The data message indicates a subscriber's desired update to a selected service. The data message is converted into a protocol compatible with a service control point. The converted data message is identical to a data message that the intelligent peripheral would create if the subscriber had entered the desired update via an interactive voice response system. The converted data message is transmitted to the service control point, which updates the service in accordance with the subscriber's update. Thus, the service is updated substantially contemporaneously with the request. Moreover, the subscriber retains the ability to update and review service data via the interactive voice response.
