MagicJack and FreePBX?

Hello we have 3 local analong lines all work on the FreePBX using the samgoma A200 card with FXO modules Finally got it setup to where it is working. However my boss the Ower wanted to setup a forth line But Verizon wanted to have a forth line just for his phone Ext. However Verizon wanted to much money. So he has a Magic Jack he brought from home I try to set it up and Call into it and i get a error message saying the Number you have dialed is a non working number. Which is strange. So i unplugged it and just hooked up a analog phone straight t the magic jack and it work i was able to call to the magic jack from my cellphone and call from the magic jack to my cellphone with no problem. I don’t see a mention of this kind of error before. Really need help can someone please help me? Thank you.

Oh i forgot we are using the forth analog port on the card also setup a new trunk for it as well as inbound and outbound for it.
