Can 2 Obi110's share the same google voice account?
Yes & no. You can set up both with the same account but the last one to connect is the one that will ring.
But you can use the "Home Office Extension" setup

Or you can have your Obi fork the call to the other Obi so they both ring at the same time.
How can you fork the call to the other Obi?
