I've been on Google Voice since its inception in 2009. It's been a rocky ride sometimes. Always found answers to my problems on the forum. Thanks mostly to SteveInWA. I noticed on Thursday the green phone LED on my OBi200 was out. No calls in or out. Got the "not receiving a response from the service provider" message. Sometimes you have to ride these out and it gets corrected, but still not working today.
Dialed **9-222-222-222 and the echo test passed. Dialed ***1 to get my IP address and find out if DHCP was enabled. The default login is admin, admin. Checked that my firmware was current. I have Google Voice on 2 cell phones and a tablet and it's working ok.
Like others, tried many times to add my device. No go.
Decided to start from scratch, deleted SP1, and did a factory reset. Still no go adding a device after multiple tries on different browsers.
On page 53 of this guide I noticed under System Status, WAN Status that the DNSServer2 was 8.8.8.8. Yeah, I know this is for an Obi202.

Under System Management and WAN Settings I set the DNSServer2 to 8.8.8.8, Saved, and Rebooted the Obi200. Went back to my account and tried to add my device. I got the same message but the Google Voice config came up this time and asked me a few questions. My Obi200 magically, or it might have been sheer luck, came back up on my dashboard and my phone is now working.
