3cx 7.x should work with the magicjack. There is a registration issue connecting; looking at log files from a server it will not register to the sip server for inbound communications due to an incorrect User Agent. I imagine the way around this is to capture the User Agent from the Magic Jack and add it to Outbound Parameters as a Custom User Agent text string. It should now register to the sip server.
