I purchased a Magic Jack Plus, registered it on my computer (as instructed), plugged it into my router and it worked perfectly without my computer running. After about 30 days, it stopped working and the only way to make/receive calls is to use it with my computer. After receiving a replacement device and registering it, the only way to make/recieve calls is to plug my Magic Jack + into my computer's USB port. I simply can't get it to work when plugged directly into my router. Is my router configuration incorrect for MagicJack +? Note that I've opened UDP ports 5060-5070 and 49152-65535. My device's IP address is 192.168.0.6.
