A cti route point with the line forwarded to unity connection should be fine. Are the questions recorded and activated? The default call handlers are open greeting, goodbye, and operator -- not sure which you mean. The default after interview action when adding an interview handler is the goodbye call handler. If you don't have the questions setup, you'd then hit the goodbye call handler.
If the cti route point is setup correctly and the interview handler is setup correctly, then instead of shotgunning it I'd fire up a port status monitor (standalone, rtmt, or telnet to port 5000) and make a test call.
