Ron,
1. I don't know how to login to the OBI device directly.
2. Most folks would assume the web access is the way to go since that is what is presented when you login to OBI.
3. I seem to have figured out the web access route settings:
a. On the web interface, do NOT modify OBiTALK Service > InboundCall Route. It should remain as is, and include a bunch of numbers (it gets these from the SP1 Services settings per Ron's earlier instructions). If you modify it to "ph" it won't work, even with step B below.
b. BELOW OBiTALK Service on the web interface is another item called AUTO ATTENDANT. On THAT item, simply uncheck the first item, which is called "Enable" . . . i.e. as you said, AUTO ATTENDANT needs to not be enabled.
c. With this change, I also found that it now also rings my cell phone. So Google Voice is working too (it apparently had been stopped by the OBI Auto Attendant).
UPDATE: Well, the above worked 1 time, then it stopped working. AutoAttendant is back.
