I have an Obi202 that I bought in August. It's been working great until now. A week or two ago, the device suddenly stopped ringing for incoming Google Voice calls. They ring my cell phone and show up in Google Talk, but the phones attached to the Obi202 don't ring. Rebooting the device (by power-cycling) fixes it, but only for a day or two. Then it stops working again and I have to reboot again.
Today I've tried to do some research, but I'm out of ideas. The firmware is up to date. The only similar forum complaints I could find seemed to be solved by checking "Forward calls to Google Chat" in the GV settings. I've had that checked all along, and I just verified that it's still set.
Any ideas for how to fix this, or for what additional diagnostics I could do? Thanks!
