The reason I posted that is:
I don't know how long ago you set up your Google Voice number(s) on your OBi, but the process changed a couple of years ago. In ye olden days, users entered their Gmail user ID and password. Google now requires that users instead use the more secure OAUTH 2.0 to authorize OBiTALK to access only the Chat (and Hangouts) service on your account, without storing your password on the portal or on the device.
To do that, you need to be signed into the Google account that holds the number you want to use. The best way to do that is to open two tabs in the same web browser, and to carefully examine the Gmail address(es) that it offers to use.
So, delete the device off of the portal, wait, reset the device, add it back to the portal, wait, and then do the Google Voice setup for each of the two Google accounts. The browser has cookies from Google pointing to the two accounts, even if you don't have a tab open, so it's vital to ensure you are using the right Google account to set up the OBi.
Note also, that after re-adding the OBi to the portal, Obihai might push the latest firmware update to the device if needed, which will cause more LED blinking and elapsed time before it's ready to configure with GV.
