I talked to OBIHAI tech support and they said Google Changed Something and I have to use the Pin for now until they can get it fixed. They also upgraded my OBI to get the stutter tone back.

Which reinforces the point that I and others have made in the past - Google and OBi aren't in communication. The OBi works with GV because the OBi engineers figured out how to make it work. Google can, and will, change GV as they sit fit without notifying OBi at all, and OBi has to then scurry and figure out a fix.
From my perspective, that means that an OBi is not the correct solution for people that rely on their phones and have no backup, or have no ability to understand how to change some of the settings when needed. It's a solution for those with some technical savvy, those of us that accept that occasional reboots and tweaks are required. I would never put one in my mother's house for example.
