Do I need to have the magic plugged in to recieve voicemail or can I set up voice mail on Magic Jack and still recieve messages while I have my other phone in?
You should be able to receive voicemails on your MagicJack number even if the MagicJack itself is off-line.
Your new MagicJack has NOTHING to do with your regular phone line, so it doesn't have anything to do with your other line or that line's ability to do anything it wants, like getting messages all to itself. :-)
Also, you don't unplug your regular phone to use MagicJack, I thought from the way you asked this("...while I have my other phone in") you might not know about this yet, but it plugs into your computer's USB port, then you plug a regular telephone into the jack on the little MagicJack box that is now hanging off your computer's USB port.
