I have an OBi100 that was configured for use with Google Voice back in January, and continued to work even after May 15th.
After reading the announcement regarding Google Voice, I found this very informative thread regarding the change in authentication protocols.
I decided to take the advice of those who suggested deleting the "old" GV setup, and then adding it back again to use the new, more secure GV authentication method.
I logged into GV, then opened another browser tab and logged into OBiTalk. From the dashboard for my device, I deleted GV from SP1, then clicked the button "Google Voice Setup". That brought up a dialog box saying that "This device needs to be upgraded to continue. Click OK to upgrade device, or CANCEL to go back". I clicked OK, which brought me to another page "Update in progress...". After about 90 seconds, I was returned to the dashboard with an error message at the top, "Failed to update device 123456789. Please try again later.", and no GV in SP1.
I've checked the OBi100 directly through it's web admin page, and it shows the software version as 1.3.0, Build 2824, which is the most current version I see listed on the website.
Dose anyone know what's going on, and how I can get GV back? Thanks.
