simple get number Sample

A simple application to use the get number action to obtain a number from an answered inbound or outbound call.

A 5 digit number containing only digits 1-6 should be entered. The help digit is set to 7. Once a valid number has been entered it is sent to a page that then reads the entered number back to the caller.

Use actions: Get Number , Play
