I got 4 calls from this number starting at 5:30, every hour. I called the number back to see who it was & I got a recorded message about magic jack but then it said this magic jack number had not been assigned to a customer. So I'm guessing it's some type of scam call. I will answer the next time they call & if it is a scam call, I will block this number from my phone. I'm so glad I found that option on my phone!!
