EUREKA!
After many attempts to re-load the firmware on the OBi110, and OBihai issuing and RMA to return the unit, we came to the conclusion the unit is defective. Since we live outside of the US, and the hassle of freight costs, shipping etc and time, we decided to open the unit for a looksy. Wow what a surprise ! There was solder resin and specks of solder on a small section of the PC board around RS17. Touching the associated chip (smaller of the two main chips), and after cleaning and a microscopic inspection, we fired it back up, couldn't keep my finger on the top of the chip because it was burning hot. No wonder that neither of the phone ports worked. This board should never have left the factory. The unit worked just fine for about 4 days. We are using 2 of them for an office telco extension. It worked great, clear voice and easy to install. DON'T register them however. We are going to order a replacement since hassling with customs , etc.and waiting for a $49 (Amazon) unit isn't worth it. On a 1 to 10 scale, I would rate this unit as a good 8. I was also impressed with the support from OBihai. Heck we all make mistakes, or at least some of us. Boone
