I connect my phone to Obihai110 and Ethernet cable and power as the instruction. But there is no dial tone, only noise. dial ***1, I can barely hear the IP from the noise. I set the Obihai110 /Google voice by following the wizard. The incoming call still ring but all noise when I pick up the phone. The outgoing phone not working. Am I lucky to have a defect one? Can some one give me some help?
