OK, thanks. Honesty, nobody has reported one way or the other if they were successful adding Google Voice to an OBi that is out of the country, while using the new Google Voice platform. At least I can tell you that outbound calling is supported, from India to other countries, but not domestically (no India<-->India calls) due to Indian telecom regulations.
Now that you have a "fresh" OBi, successfully added to the portal, what happens if you try again to add Google Voice via the OBiTALK portal?
