Suspicion confirmed.
"Yahoo! Help - Yahoo! Messenger - Voice Chat
Yahoo! Messenger for Macintosh does not include the Voice Chat feature. We are aware there is strong interest among our Macintosh users, but there is currently no schedule for releasing this feature."
absolut78, make sure your professor knows that the software doesn't support this "course requirement" on your platform. It
should make a difference to him/her. If the functionality is a requirement of the course, then the school or professor should have done the research to find out that only the Windows client supports voice chat. All I had to do was use Yahoo's "Ask Yahoo! Help" function to get this information; it took me all of one minute to confirm that the Mac client doesn't support voice messaging.
A believe that there are other chat clients that do support voice chat on the Mac, and that also interface with Yahoo, but I haven't researched that subject yet. Maybe you could get extra credit for providing this "fix."
