simple run speech menu Sample

A simple application that presents an audio menu to an answered inbound or outbound call.

Options 1 and 2 direct to a page that reads out a weather report for the selected country (Belgium or Venezuala). Option 3 directs to a page that read out a weather report for Outer Mongolia. Each page then returns to the menu page.

If no selection or an invalid selection is made the caller is prompted to re-select. After several attempts the caller will be played an audio file (oneMoreTime.wav) prompting for a final go.

This application requires the wav file oneMoreTime.wav to be available in the cloud media store.

Uses actions: Run Speech Menu, Play, Redirect
