Possible work around until this is fixed properly.
I'll quote myself here:
For those suffering severe battery draining when using the OBiON on the various smart phones, this should also be a work around solution if the OBiON is too resource hungry on the smart phone. There is a GTALK app available for these smart phones. You might loose some ability without the OBiON, at least you will be able to make outgoing calls using the OBi AA.
@QBZappy, what is the GTALK app that you were referring to in your post? I too am experiencing fast battery drain. I have tried Talkatone on my iPhone, but then my Obi 100 at home no longer rings when I have an incoming GV call. Is there a way to use Talkatone with the Obi service?
Does anyone know if there's a way to have ObiON notify you of an incoming call even if your iPhone is in locked mode?
