Your OBi110 device is an End-of-Life OBi model:
http://blog.obihai.com/Instead of trying to get that up and running, consider replacing that OBi110 device with a OBi2 series, such as OBi200 or OBi202. These OBi200 device or OBi202 device has many more features and will allow you to add up to 4 Google Voice accounts also.
Will save you a lot more time.
