Hi, I pair my Plantronics Calisto PLT Headset to my Desktop Computer (Windows 7 x64), and it showed that everything is OK, but when I tried to use it, it didn't work. When I press icon of sound on the taskbar and I go to Playback or Recording there is there Bluetooth Hands-free Audio but is Disconnected, and I don't have any idea how to connect this and make to work. Can someone help me to solve this problem? I will really appreciate any help. P.S. I did everything like supposed to be. I attached few images to show my situation.
