Step 1 was ok on both of my 110 boxes (GV configured correctly with actual number and chat checked). Neither box was ringing on incoming calls, but both would make calls just fine.
I deleted both boxes from the Obi account, and added the first without issue. Upon doing so, incoming calls started to ring just fine.
On my second box, I can't seem to get it to register with Obi using the add device feature. I dial the **5 XXXXXXX number, and it says it's registered the number with the server, but it times out on the web page. I tried the **9 222 222 222 echo test as suggested, and it works just fine. I power cycled the box, and retried.
As a last resort, I logged into the box using the LAN IP and did a reset configuration. Rebooted, and reattempted everything. Same results - with the echo test still working.
Did I just boff my box?
Edited to add: After a few more attempts, it finally took. I'm now registered. HOWEVER, I still am not receiving calls on the box. I can make them fine. What else can I check?
Edited again: Having done nothing else, it suddenly started working. Perhaps GV is just having issues at the moment. Figures. Usually when I'm doing any kind of network testing, Murphy will have my ISP go down so that I think it's my network...
