This thread has become a cesspool of ranting and whining and posting a lot of incoherent information. Stop already. Enough.
Look: all that matters, is the you're having some sort of problem on your 508s. I already said, repeatedly, that it could have been one of several issues, which could have been caused by either company.
As of around 5pm PT Friday, the problem was identified, and the fixed firmware build was being pushed out.
If your device or one or more of its Service Provider configurations isn't working with a given Google account/GV number, then follow the usual steps to delete that SP off of your dashboard, wait for the device to reboot, then follow the steps to click on the SPx, select Google Voice to configure, and complete the steps.
Important: Since you have multiple Google accounts, and Google allows you to be signed into multiple accounts on the same web browser, you should open an "Incognito" browsing window on Google Chrome Browser by pressing Ctrl-Shift-N, or opan a "Private" browsing window on Firefox by pressing Ctrl-Shift-P. Sign into only one of the accounts in one tab, open another tab and sign into the OBiTALK portal. Repair that configuration and any others on this Google account. Then, close the incognito/private window to remove those accounts, and reopen the window, repeat the steps if necessary, until you're done.
