Whenever there is voice mail in google voice, voice mail indicator shows up on the phone. I check voice mail and delete it, there's nothing whatsoever in GV's inbox, no voice mails, missed calls, messages, or anything else, but indicator does not go away. But it disappears at once when I open obi control panel in browser, without making any changes.
I saw articles about this problem; the setting "'Place missed calls in the inbox" is off in my GV account.
