Yes, 'Chat' is selected in the Google Voice. My GV number rings on my obi just fine. My cellphone receives calls just fine with my carrier unique number. My cellphone also receives GV calls through Hangouts just fine.
It is the Bluetooth with Obi that is no longer working.
I pair my cellphone via the built in Bluetooth of the Obi1062 phone. In the past, when my cell number - (my carrier's number - not the GV) received a call, it would ring both the cell and the Obi -- using the Obi as a headset, if you will. Now they are paired; but, the cell doesn't ring on the Obi. I can see the Obi as an audio device on my cell phone; but, when I select it, the call audio does not go through the Obi. My caller is just put on hold, if you will.
Yes, 'ph' with the quotes is in the InBoundCallRoute for Bluetooth.
