...Today, my wife and I are driving to a department store when I decide to call a friend on my cell phone w/ the connected hands-free headset to ask him a question. My friend doesn't pick up the phone, so I leave a message on his voice mail and finish by pressing a button on the headset to disconnect the call. Immediately afterwards, my wife and I start a conversation on how big of a jackass that our friend has been acting lately, and how much we dislike his arrogant wife. Well, after about a 90-second rant between me and my wife about our disappointment w/ our friend and his wife - things that we would never tell them to their face, I hear an unexpected "beep" in my headset followed by the automated female "voice" telling me: YOUR MESSAGE HAS BEEN DELIVERED. The button on the headset didn't disconnect the call like it should have!!! !!! Well, we've got some explaining to do. Hope this helps someone not to trust that stupid non-functioning headset feature, and guard your confidentiality and privacy.
