We've released two new VAD tools IVR components. Design components for your tool box for the 3CX Voice Application Designer.
There's the MoveFile component, that lets you move any file (such as an audio file that the IVR might create) to any other location on the server or network where the web server has access.
The other one, Speak Digits, will use basic text-to-speech and let you play back the digits that a user enters.
