First off let me ask how many people have or have tried the MagicJack? and for those of you who have then you know how sweet it would be to have and iphone app that works with your MagicJack account for Voip Calling and receiving.... Developers Please this would be a money maker for you....

im pretty sure the iphone does not support the hardware needed for that. the magicjack is completely hardware....not software. you couldnt really make an app for that. why not just ask the dev's of like siax to add this protocol to thier app if they dont already have it and then just use it like any other voip service????

Since this was the top search response, and it doesnt help.
I'd like to add that, you can use SIAX or Siphon to use this SIP related Phone service. Although i havent made it work just yet- there are plenty of resources out there that show how to make it work. only thing u have to worry about is, QOS!

my friend has magicjack and uses siphone to connect to it
