Abstract: A method, apparatus and computer program product for providing remote end input validation is presented. A communication is sent to an IVR from a remote end device. The IVR responds by sending a Request Voice Data Capsule (request VDC) to the remote end device. The remote end device receives the Request Voice Data Capsule (request VDC) from the IVR and executes a contained in the remote VDC. The remote end communications device validates user inputs utilizing a resource associated with said remote end communications device and sends a Response Voice Data Capsule (response VDC) including at least one validated communication to the IVR. The IVR processes the response VDC.
