IVR supports thousands of choices

I would like to use your software to provide playback of wav files to callers. I need to have the caller be able to choose from many files, perhaps numbering in the thousands. How many wav files can a caller access? It would appear he or she may be limited to pressing the 0-9 keys to make a choice. Is there a way to expand the choices for the caller?

Yes, instead of using the Choice element, use the Digits element. A digits element allows caller input of any length of digits that is ended by a pound sign (#). The captured digits (without the pound sign) can then be used to select your audio files.

The password sample uses the digits element.
