I have been using the obi100 for about 4 months. My setup is with GV and I use a phone splitter to connect one phone in the same room as the obi and the other connection goes to the phone wall outlet, allowing other phones in the house to ring. This setup has worked fine since it was installed but today noticed no dial tone on any phone. The obi showed the phone light flashing indicating in use but no phone was being used. I reset the obi and re-entered the device via the web portal. I can now connect a phone directly into the obi and make and receive calls but as soon as I connect a telephone line from an outlet, (even without the phone splitter) the obi starts flashing as in use.
Any thoughts or settings that need to be enabled?
