Yesterday I noticed my phone wasn't ringing on incoming calls, I picked up the handset and no dial-tone. Comparing the caller Id on my phone with the GV call logs, it looks like the problem started back on Jun 3. I started looking in the Obi forums and found references to the new fw upgrade (2886). I performed a factory reset and upgraded the fw successfully. I then removed the device from the Obihai Dashboard and attempted to re-add, but it's not able to connect, and I'm still not getting a dial-tone. Power light is solid green, phone light is off. I've tried putting the Obi IP in the DMZ, tried a different phone, but nothing works. I'm stuck. Any help appreciated. Thanks.
