Magicjack is not reliable and the company does not stand behind their product. I have spent over a dozen hours on chats trying to keep it working. After a host of changes to my settings that their agents walk me through I could get the unit working, but usually it would quit after a few days. After 2 months of trying to make it reliable I asked for a refund and was denied, now I am waiting for a replacement but have seen a number of complaints posted because they charge you for the replacement, then deny that they received the returned unit and will not give you your refund. I am now wondering if I will cancel the replacement and just chalk this up to my stupidity and their lack of integrity.
