Seems there has been no solution for this. I will just add the following:
1) It is still an issue.
2) All I did was switch from an OBi100 to an OBi200. On my OBi100, I just deleted the SP1 service and then deleted the device. Swap the 200 for the 100. Then add the device and configure for GV. The exact same GV, nothing changed there.
Then I see the USELESS "Out of Area" in large letters followed by the tiny CID number. I'm using a Panasonic cordless.
3) Reverse the process to return to my trusty OBi100 (delete service, delete device, swap the 100 back, then add device and configure for GV.)
4) Now all is well again. When I receive a call, I now see either the incoming number or the caller's name(not sure where that comes from- maybe my speed dials) in large letters so I can see who is calling without a magnifying glass.
5) What a waste of money shelling out for the OBi200. Bought it so that my old DirecTivo analog modem could dial into Tivo again. That didn't work either. If you have an OBi100, don't waste your money on a 200. THE OBi100 IS BETTER.
