Thanks for the help!
I don't know how to set Obi rules for incoming calls, so I don't think there are any rules set.
My father inlaw says he has caller id. I asked him to call my cell phone # to verify it, and it also went straight to VM. So I have two phones (1 Google Voice 1 Google Fi) sending this one number to voice mails.
Another interesting event is that when dad calls in and I am logged into Google Fi, my laptop rings
I got an email directing me to delete and add the Obi device. I will try that first. Do you think there may be a connection to having both Google Voice with the Obihai200 and my cell phones with Google Fi? There are different email accounts connected to them. After I delete and re-install, should I concider porting my Google Voice # to Google FI?
