Same dead-phone problem, different cable end. Your Grandstream device takes a USB Micro-B connection and the original plug pack's gone. This is the 5V USB Micro-B replacement with an Australian AS3112 two-pin wall plug. No adapter, no hunting for a laptop USB port. Plug in, power up, done. Add to cart
