not sure what has changed (i only noticed this recently) but i can hear ALL my skype noises -- alerts, chat noises, etc, etc) when i am on a phone call through my magicjack. i use a wired handset, WHAT'S GOING ON???
Check in Skype -> Tools -> options -> audio settings and make sure that 1) its not set to the Tigerjet device or 2) if its set to the Windows default device that the "default device" is not the Tigerjet.
