[callmemage]

I try to make my magicjack use my phone "usb phone tigerjet" but it wont let me. Magicjack has destroyed my good ol use of my headset as it cant use my headset and its also trying to use it. its only depending on my headset because when i unplug it it says it needs and audio device! no problem with microphone, but another dude with the same post couldnt be helped as it is a common problem in vista! HELP! i need my headset back!
