Many softphone applications, including Skype have settings to select a specific audio device for VoIP calls. Consult your softphone instructions to find out how to change the audio device it uses. You should first plug in the USB adapter, then change the softphone's default audio devices to "Plantronics BT adapter". Skype have useful information on setting up audio devices here: NOTE: If you do not use the headset button to answer and end calls on your computer, please be sure to keep an eye on the USB adapter. If the blue light is solid then the headset is in standby mode conserving battery. To get the headset into talk mode, click the call button on the headset and the blue light on the dongle will then start to flash.
