DSLReports.com is one of my favorite places to find help with my high speed internet connection and voip challenges. It’s no surprise that the also have a sub-forum directly focused on the needs of magicJack owners. You may find that the same helpful and friendly people who hang out here also hang out at the unofficial magicJack support forum as well.
My majic jack worked at first with either phone, now it won’t work with either phone the phones say: Linei n use all the time. I think something with the MJ cancelled out or broke the phones, it doesn’t make sense that two phones that worked prior don’t work at all now, and the common denominator is the new Magic Jak Plus.
