Looks like Skype has some more security issues. Andy had an "eavesdropping" security issue when he tried calling another Skype user.
Essentially when he dialed this other Skype user, this user was already in a Skype conference call, so Andy started to leave a message. Apparently, the Skype conference participants could hear Andy! Not only that, but Andy could also hear the Skype participants that were conferencing. This is a scary thought to think that someone leaving a Skype voice message could eavesdrop on a ongoing Skype call.
