IVR customer service hotline diagram

"Outbound calling. IVR systems can be used for outbound calls, as IVR systems are more intelligent than many predictive dialer systems, and can use Call Progress Detection to recognize different line conditions as follows: (1) Answer (the IVR can tell the customer who is calling and ask them to wait for an agent); (2) Answered by voice mail or answering machine (in these circumstances the IVR system can leave a message); (3) Fax tone (the IVR can leave a TIFF image fax message); (4) Divert messages (the IVR will abandon the call); (5) No answer." [Interactive voice response. Wikipedia] The IVR customer service hotline diagram example was created using the ConceptDraw PRO software extended with the Interactive Voice Response Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.
