Thought I would share this in the interests of saving folks time. I had installed my Obi202 and configured my Google Voice (GV) number. Was able to dial out and the receiving caller ID displayed the number correctly. But when trying to call in found that calls coming from AT&T and Verizon did not ring or connect although TMO did. Also found that calls from Skype and Google did ring through and connect.
Obihai Support responded to my email within minutes (wow!) and provided the fix below which worked. So—implication is that my Google Talk was, in some way, corrupted.
Please try to re-add your Google Chat again:
1. Login to your Google Voice account
2. Go to "Settings" located on the top right (cog wheel)
3. On the Phone tab, you will see a "Delete" option under Google Chat
4. Click "Delete" Google Chat
5. Open a new browser and login in to www.gmail.com using your Gmail account.
You will see Gmail Call Phone (located on the bottom left corner).
6. Make a call out from your Gmail Call Phone
7. Once you have done so, you should appear again in https://www.google.com/voice#phones
8.Make sure to check the checkbox for Google Chat
Try calling your Google Voice number againThanx Obihai support!
