I have set up my OBi and it works great with one phone connected. I want to get my other landline phones to work as well, so I connected the RJ-11 telephone line cable to the line port. I also unplugged my outside lines in the telco box. The line port did not light up when plugged into the phone jack, and none of my other phones worked. So, should I leave my outside lines plugged in and then plug in the line port? Help please as this is becoming very frustrating. As a side note I am still connected to Cox's digital phone service, but want to dump them and use the OBi as my new landline. Hope this makes sense.
