Both units are using different GV accounts so that shouldnt be the problem.. The setup to the best of my understanding is supposed to ring both Obi boxes when A call comes in on the main GV number (we don't use the secondary GV account for anything but outbound calls)
I have set things up exactly as instructed in the thread and both phones do ring, but like I said when we go to answer the call we get a dial tone and on the calling end we get the Obi attendant after a few rings.
