I just got this Obi. I connected it to the router, which is connected via WAN to the internet. I followed the instructions exactly and there is a solid green power LED light on the device. It is a corded phone. There is no dial tone or anything when you pick up the phone. Nothing happens (there are no tone sounds when pressing the numbers) when I try to do **9222222222 or add device and enter **5 WXYZ. The add device attempt to connect eventually times out. What could be the problem with this?
Please contact Obihai support to troubleshoot and resolve the issue.

Having the exact same problem.
I will add that I opened the TCP and UDP ports as instructed in the FAQ, tried moving the Obi100 to the DMZ all with no luck.
Also, I tried updating the firmware on the Obi. After, found a setting that told me the attached phone was "on the hook". I tried lifting the phone from the receiver but still got the same message after refreshing.
I have sent in a ticket from the above link.
