I connected the black wire between the OBI110's "line" jack and the landline jack in the wall but none of the other jacks in the house went live. The device itself works. I have a phone plugged into its "phone" jack, and can make and receive calls.
I haven't had a traditional land line for years, but have been using the interior wiring with a Terk Leapfrog (not the wireless version) with great success, and the MagicJack as well.
Any ideas?
Thanks!
