I continue to be amazed by the OBi100. In my transition to VoIP I lost some minor features of my POTS service. One of these was that I had AT&T's Ring Master Service.
RingMaster service enables two or three telephone numbers to share one line. A unique ringing pattern is provided for each of the additional numbers. This allows a customer to determine prior to answering a call, which number the calling party has dialed.
What I had done was to have my business Google Voice number forwarded to one of my Ring Master numbers. This way I could tell whether the incoming call was for my personal number or my business number.

Plan A was to have the business Google Voice number have the new home Google Voice number as a forwarding number but Google Voice won't let you do that.

Plan B was to just take all the calls to the business Google Voice number on my cell phone. That worked but cost me airtime and talking on the cell phone is not as comfortable as on a traditional handset.

Time for Plan C.

A quick Google of "obi100 multiple google voice accounts" turned up this forum post. Better yet "bgt23" answered his own question.

The OBi devices support TWO VoIP services. So I just went back to and connected the second adapter to the business Google Voice account.

2 minutes later it was all working. And by default the ring tones are different.


PS. There's another twist coming in this saga.
