Thanks for everyone's help. I think I have everything working perfectly (or semi-perfectly). When my GV number is called, it rings to both phone and iPhone. When my wife's GV number is dialed, it rings only on her phone. the OBi110 is a super-configurable system and so far is working great. I know that there are differences of opinion on how things get done, but it's working for me so I'm a happy camper (and calling the USA for free from the Turks and Caicos)
