The predefined VoiceXML scripts (up to 10 different scripts aresupported) determine the development of the call according to the caller’s responses (DTMFdigits) and AAA (Authentication, Authorization and Accounting) information exchanged with aRADIUS server. Interaction with the caller is conducted using a set of audio messages (stored ina single Voice Prompts file in the gateway’s flash/RAM memory) on the gateway’s side, and bypressing DTMF digits on the subscriber’s side.K.4.1 Basic Calling Card IVR ScenarioFigure K-2: Basic Call ScenarioNote: Some messages have been omitted from the above drawing for the sake ofclarity.
