Please read further, as this is not the same issue that's been described in several other recent posts, like this one:
http://www.obitalk.com/forum/index.php?topic=13761.0Yesterday morning and this morning (4/10, 4/11), my parents' Obi200 failed to ring when I called their Google Voice number. GV also rings mom's cell phone, which did work properly.
This has happened before, and just seems to happen every once in a while.
The new twist, though, is that during these same mornings, outgoing calls were also not working properly. Mom would dial a number from the home phone, she would hear one ring but then the call would disconnect. When she was dialing my mobile number, for instance, I would see the call coming in on my phone and would answer it (if I was quick enough) but then I would hear a click and my phone would indicate that the call disconnected. But if she called me from her mobile phone (not using GV), then no issue.
I asked her to try calling me via her Google Home Mini, which is on the same home network, and is configured to use the same GV account as the Obi. That worked properly. (It rang, and she was able to complete the full call.)
During the issue this morning, we tried power cycling the Obi200, but that did not change the symptoms.
By evening (on both days), the problem has resolved by itself.
We've made no configuration changes since setting up the Obi200 last year. It replaced an Obi110 which worked for a couple years until the Google certs change killed it.
Any suggestions?
