You can test your voice applications either using a third-party VoiceXML gateway or SAP Text Application Gateway (STAG).
To test your voice application using a third-party VoiceXML gateway you must install a third-party VoiceXML gateway and configure it with the voice application URL.
More information: Refer to third-party VoiceXML gateway documentation.
To test your voice application using STAG, you must have compiled and deployed your voice application.
