Magicjackhelpdesk?

Well for me, give up, their support help is poor and none, and that is just on good days They are cheap for a reason, you can't get any real help.

But of course if you want to try, here is their web site and help desk
magicJack - Customer Care - Official Website

They were wanting me to turn off a lot of my security to make the phone work ( a couple of years ago when I tried it)
